[Question] How to use different filesystem between checkpoint data and user data sink

ouywl
Hi all,
    We have implemented a filesystem plugin for sink data to hdfs1, and the yarn for flink running is used hdfs2. So when the job running, the jobmanager use the conf of hdfs1 to create filesystem, the filesystem plugin  is conflict with flink component. 
    We implemeted step:
      1.  ‘FileSystemEnhance’ is implement from “FileSystem”
      2.  ‘FileSystemFactoryEnhance’ is implement from “FileSystemFactory”,add kerberos auth in ”FileSystemFactoryEnhance" 
      3. Add a service entry. Create a file META-INF/services/org.apache.flink.core.fs.FileSystemFactory which contains the class name of “ FileSystemFactoryEnhance.class”

And  the job mainclass is :
   “ public static void main(String[] args) throws Exception{
    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    env.enableCheckpointing(60*1000);
    env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
    env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
    env.getConfig().enableSysoutLogging();


    Properties props = new Properties();
    props.put("bootstrap.servers", SERVERS);
    props.put("group.id", GROUPID);
    props.put("enable.auto.commit", "true");
    // props.put("auto.commit.interval.ms", "1000");
    props.put("session.timeout.ms", "30000");
    props.put("auto.offset.reset", "latest");
    props.put("key.deserializer", org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.deser.std.StringDeserializer.class.getName());
    props.put("value.deserializer", StringDeserializer.class.getName());
    FlinkKafkaConsumer010 consumer011 = new FlinkKafkaConsumer010<String>("zyf_test_2", new SimpleStringSchema(), props);
    DataStream<String> source = env.addSource(consumer011).setParallelism(1);

    source.print();
    Thread.currentThread().getContextClassLoader();

    StreamingFileSink sink = StreamingFileSink
            .forRowFormat(new Path("hdfs://bdms-test/user/sloth/zyf"), new SimpleStringEncoder<>("UTF-8"))
            .build();

    source.addSink(sink);

    env.execute();
}”

And start the job, the jobmanager filesystem is error, the log means the jobmananger use “FileSystemFactoryEnhance” filesystem and confict.

Hi ouywl,

>>    Thread.currentThread().getContextClassLoader();
What does this statement mean in your program?

In addition, can you share your implementation of the customized file system plugin and the related exception?

Best,
Vino

Re: [Question] How to use different filesystem between checkpoint data and user data sink

Yang Wang
You could have a try the new plugin mechanism.
Create a new directory named "myhdfs" under $FLINK_HOME/plugins, and then put your filesystem related jars in it.
Different plugins will be loaded by separate classloader to avoid conflict.

Yang

Re: [Question] How to use different filesystem between checkpoint data and user data sink

Piotr Nowojski-3
Hi,

As Yang Wang pointed out, you should use the new plugins mechanism.

If it doesn’t work, first make sure that you are shipping/distributing the plugins jars correctly - the correct plugins directory structure both on the client machine. Next make sure that the cluster has the same correct setup. This is especially true for the standalone/cluster execution modes. For yarn, mesos, docker the plugins dir should be shipped to the cluster by Flink itself, however Plugins support in yarn is currently semi broken [1]. This is already fixed, but waiting to be released in 1.9.2 and 1.10.

If it still doesn’t work, look for TaskManager logs what plugins/file systems are being loaded during the startup. If none, that's the problem.

Hi,

Can you share the full stack trace or just attach job manager and task managers logs? This exception should have had some cause logged below.

Hi all,
    We have implemented a filesystem plugin for sink data to hdfs1, and the yarn for flink running is used hdfs2. So when the job running, the jobmanager use the conf of hdfs1 to create filesystem, the filesystem plugin  is conflict with flink component. 
    We implemeted step:
      1.  ‘FileSystemEnhance’ is implement from “FileSystem”
      2.  ‘FileSystemFactoryEnhance’ is implement from “FileSystemFactory”,add kerberos auth in ”FileSystemFactoryEnhance" 
      3. Add a service entry. Create a file META-INF/services/org.apache.flink.core.fs.FileSystemFactory which contains the class name of “ FileSystemFactoryEnhance.class”

And  the job mainclass is :
   “ public static void main(String[] args) throws Exception{
    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    env.enableCheckpointing(60*1000);
    env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
    env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
    env.getConfig().enableSysoutLogging();


    Properties props = new Properties();
    props.put("bootstrap.servers", SERVERS);
    props.put("group.id", GROUPID);
    props.put("enable.auto.commit", "true");
    // props.put("auto.commit.interval.ms", "1000");
    props.put("session.timeout.ms", "30000");
    props.put("auto.offset.reset", "latest");
    props.put("key.deserializer", org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.deser.std.StringDeserializer.class.getName());
    props.put("value.deserializer", StringDeserializer.class.getName());
    FlinkKafkaConsumer010 consumer011 = new FlinkKafkaConsumer010<String>("zyf_test_2", new SimpleStringSchema(), props);
    DataStream<String> source = env.addSource(consumer011).setParallelism(1);

    source.print();
    Thread.currentThread().getContextClassLoader();

    StreamingFileSink sink = StreamingFileSink
            .forRowFormat(new Path("<a href="hdfs://bdms-test/user/sloth/zyf" class="">hdfs://bdms-test/user/sloth/zyf"), new SimpleStringEncoder<>("UTF-8"))
            .build();

    source.addSink(sink);

    env.execute();
}”

And start the job, the jobmanager filesystem is error, the log means the jobmananger use “FileSystemFactoryEnhance” filesystem and confict.

As the url https://ci.apache.org/projects/flink/flink-docs-stable/ops/filesystems/#pluggable-file-systems how to avoid use “Thread.currentThread().getContextClassLoader()"

Re: [Question] How to use different filesystem between checkpointdata and user data sink

In reply to this post by ouywl
Hi Piotr:
     As debug the code, I found The jobmanager classpath is not content “system-plugin.jar”, But when run `configureFileSystems(configuration)` in `ClusterEntrypoint.startCluster()`, It will initialize with the FileSystem plugin in the method 'FileSystem.initialize(configuration, PluginUtils.createPluginManagerFromRootFolder(configuration));’,  After that when blob getFilesystem,It will load FileSystem by schema, So it will call “MyFileSystemFactory” which implements myself, and It have put core-site.xml, hfs-site.xml in “system-plugin.jar”, It is not  Suitable for ‘hdfs://slothTest/user/sloth/HA/’ 。

Full stack is :
  Log Type: jobmanager.log

Hi,

As Yang Wang pointed out, you should use the new plugins mechanism.

If it doesn’t work, first make sure that you are shipping/distributing the plugins jars correctly - the correct plugins directory structure both on the client machine. Next make sure that the cluster has the same correct setup. This is especially true for the standalone/cluster execution modes. For yarn, mesos, docker the plugins dir should be shipped to the cluster by Flink itself, however Plugins support in yarn is currently semi broken [1]. This is already fixed, but waiting to be released in 1.9.2 and 1.10.

If it still doesn’t work, look for TaskManager logs what plugins/file systems are being loaded during the startup. If none, that's the problem.

Create a new directory named "myhdfs" under $FLINK_HOME/plugins, and then put your filesystem related jars in it.
Different plugins will be loaded by separate classloader to avoid conflict.


Best,

Hi ouywl,

>>    Thread.currentThread().getContextClassLoader();
What does this statement mean in your program?

In addition, can you share your implementation of the customized file system plugin and the related exception?

Best,
Vino

Hi all,
    We have implemented a filesystem plugin for sink data to hdfs1, and the yarn for flink running is used hdfs2. So when the job running, the jobmanager use the conf of hdfs1 to create filesystem, the filesystem plugin  is conflict with flink component. 
    We implemeted step:
      1.  ‘FileSystemEnhance’ is implement from “FileSystem”
      2.  ‘FileSystemFactoryEnhance’ is implement from “FileSystemFactory”,add kerberos auth in ”FileSystemFactoryEnhance" 
      3. Add a service entry. Create a file META-INF/services/org.apache.flink.core.fs.FileSystemFactory which contains the class name of “ FileSystemFactoryEnhance.class”

And  the job mainclass is :
   “ public static void main(String[] args) throws Exception{
    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    env.enableCheckpointing(60*1000);
    env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
    env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
    env.getConfig().enableSysoutLogging();


    Properties props = new Properties();
    props.put("bootstrap.servers", SERVERS);
    props.put("group.id", GROUPID);
    props.put("enable.auto.commit", "true");
    // props.put("auto.commit.interval.ms", "1000");
    props.put("session.timeout.ms", "30000");
    props.put("auto.offset.reset", "latest");
    props.put("key.deserializer", org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.deser.std.StringDeserializer.class.getName());
    props.put("value.deserializer", StringDeserializer.class.getName());
    FlinkKafkaConsumer010 consumer011 = new FlinkKafkaConsumer010<String>("zyf_test_2", new SimpleStringSchema(), props);
    DataStream<String> source = env.addSource(consumer011).setParallelism(1);

    source.print();
    Thread.currentThread().getContextClassLoader();

    StreamingFileSink sink = StreamingFileSink
            .forRowFormat(new Path("<a href="hdfs://bdms-test/user/sloth/zyf" class="">hdfs://bdms-test/user/sloth/zyf"), new SimpleStringEncoder<>("UTF-8"))
            .build();

    source.addSink(sink);

    env.execute();
}”

And start the job, the jobmanager filesystem is error, the log means the jobmananger use “FileSystemFactoryEnhance” filesystem and confict.

As the url https://ci.apache.org/projects/flink/flink-docs-stable/ops/filesystems/#pluggable-file-systems how to avoid use “Thread.currentThread().getContextClassLoader()"
