Flink 1.1.0 : Hadoop 1/2 compatibility mismatch

LINZ, Arnaud

Hello,

 

I’ve switched to 1.1.0, but part of my code doesn’t work any longer.

 

Despite the fact that I have no Hadoop 1 jar in my dependencies (2.7.1 clients & flink-hadoop-compatibility_2.10 1.1.0), I have a weird JobContext version mismatch error, that I was unable to understand.

 

Code is a hive table read in a local batch flink cluster using a M/R job (from good package mapreduce, not mapred).

 

import org.apache.hadoop.mapreduce.InputFormat;

import org.apache.hadoop.mapreduce.Job;

import org.apache.flink.api.java.hadoop.mapreduce.HadoopInputFormat;

(…)

        final Job job = Job.getInstance();

        final InputFormat<NullWritable, DefaultHCatRecord> hCatInputFormat = (InputFormat) HCatInputFormat.setInput(job, table.getDbName(), table.getTableName(), filter);

 

        final HadoopInputFormat<NullWritable, DefaultHCatRecord> inputFormat = new HadoopInputFormat<NullWritable,

        DefaultHCatRecord>(hCatInputFormat, NullWritable.class, DefaultHCatRecord.class,  job);

 

 

        final HCatSchema inputSchema = HCatInputFormat.getTableSchema(job.getConfiguration());

        return cluster

            .createInput(inputFormat)

            .flatMap(new RichFlatMapFunction<Tuple2<NullWritable, DefaultHCatRecord>, T>() {                    

                    @Override

                    public void flatMap(Tuple2<NullWritable, DefaultHCatRecord> value,

                        Collector<T> out) throws Exception { // NOPMD

                        (...)

                    }

                }).returns(beanClass);

 

 

Exception is :

org.apache.flink.runtime.client.JobExecutionException: Failed to submit job 69dba7e4d79c05d2967dca4d4a27cf38 (Flink Java Job at Tue Aug 09 09:19:41 CEST 2016)

Re: Flink 1.1.0 : Hadoop 1/2 compatibility mismatch

Ufuk Celebi
As noted in the other thread, this is a problem with the Maven
artifacts of 1.1.0 :-( I've added a warning to the release note and
will start a emergency vote for 1.1.1 which only updates the Maven
artifacts.

Re: Flink 1.1.0 : Hadoop 1/2 compatibility mismatch

Ufuk Celebi
I've started a vote for 1.1.1 containing hopefully fixed artifacts. If
you have any spare time, would you mind checking whether it fixes your
problem?

The artifacts are here: http://home.apache.org/~uce/flink-1.1.1-rc1/

You would have to add the following repository to your Maven project
and update the Flink version to 1.1.1:

<repositories>
<repository>
<id>flink-rc</id>
<name>flink-rc</name>
<url>https://repository.apache.org/content/repositories/orgapacheflink-1101</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>

Would really appreciate it!

Hi,
Good for me ; my unit tests all passed with this rc version.
