AbstractMethodError while writing to parquet

[Jan Oelschlegel]

Hi at all,

 

i’m using Flink 1.11 with the datastream api. I would like to write my results in parquet format into HDFS.

 

Therefore i generated an Avro SpecificRecord with the avro-maven-plugin:

<plugin>
                <groupId>org.apache.avro</groupId>
                <artifactId>avro-maven-plugin</artifactId>
                <version>1.8.2</version>
                <executions>
                    <execution>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>schema</goal>
                        </goals>
                        <configuration>
                            <sourceDirectory>src/main/resources/avro/</sourceDirectory>
                            <outputDirectory>${project.basedir}/target/generated-sources/</outputDirectory>
                            <stringType>String</stringType>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

 

 

Then  I’m using the SpecificRecord in the StreamingFileSink:

val sink: StreamingFileSink[SpecificRecord] = StreamingFileSink
  .forBulkFormat(
    new Path("hdfs://example.com:8020/data/"),
    ParquetAvroWriters.forSpecificRecord(classOf[SpecificRecord])
  )
  .build()

 

 

The job cancels with the following error:

Hi Jan,

it looks to me that you might have different parquet-avro dependencies on your class path. Could you make sure that you don't have different versions of the library on your classpath?

Cheers,

Till

Hi Till,

 

thanks for hint. I checked it and found a version conflict with flink-parquet.

 

With this version it is running:

 

 

<dependency>
    <groupId>org.apache.parquet</groupId>
    <artifactId>parquet-avro</artifactId>
    <version>1.10.0</version>
</dependency>

 

 

But how can I avoid this in the future? I had to add parquet-avro, because without there were some errors. Do I have to lookup such conflicts manually and then choose the same version like at flink dependencies ?

 

 

Best,

Jan

I guess it depends from where the other dependency is coming. If you have multiple dependencies which conflict then you have to resolve it. One way to detect these things is to configure dependency convergence [1].

Hi Jan,

 

it looks to me that you might have different parquet-avro dependencies on your class path. Could you make sure that you don't have different versions of the library on your classpath?

 

Cheers,

Till

Okay, this is helpful. The problem arrives when adding parquet-avro to the dependencies. But the the question is, why do I need this dependency? I is not mentioned in the docs and I’m using standard setup for writing into hdfs with parquet format, nothing special.

 

 

Best,

Jan

I guess it depends from where the other dependency is coming. If you have multiple dependencies which conflict then you have to resolve it. One way to detect these things is to configure dependency convergence [1].

Hi Till,

 

thanks for hint. I checked it and found a version conflict with flink-parquet.

 

With this version it is running:

 

 

<dependency>
    <groupId>org.apache.parquet</groupId>
    <artifactId>parquet-avro</artifactId>
    <version>1.10.0</version>
</dependency>

 

 

But how can I avoid this in the future? I had to add parquet-avro, because without there were some errors. Do I have to lookup such conflicts manually and then choose the same version like at flink dependencies ?

In order to answer this question you would need to figure out where the second parquet-avro dependency comes from. You can check your job via `mvn dependency:tree` and then check whether you have another dependency which pulls in parquet-avro. Another source where the additional dependency could come from is the deployment. If you deploy your cluster on Yarn, then you can get the Hadoop dependencies on your classpath. This is another thing you might wanna check.

Cheers,

Till

I checked this up in IntelliJ with the Dependency Analyzer plugin and got the following insights:

 

There are to conflicts: one with parquet-column and one with parquet-hadoop:

 

 

 

 

 

There you can see, why it is running with version 1.10.0 of parquet-avro. But as I said, if I remove the parquet-avro dependency, there will be another error.

 

 

Best,

Jan

In order to answer this question you would need to figure out where the second parquet-avro dependency comes from. You can check your job via `mvn dependency:tree` and then check whether you have another dependency which pulls in parquet-avro. Another source where the additional dependency could come from is the deployment. If you deploy your cluster on Yarn, then you can get the Hadoop dependencies on your classpath. This is another thing you might wanna check.

 

Cheers,

Till

I guess it depends from where the other dependency is coming. If you have multiple dependencies which conflict then you have to resolve it. One way to detect these things is to configure dependency convergence [1].

Hi Till,

 

thanks for hint. I checked it and found a version conflict with flink-parquet.

 

With this version it is running:

 

 

<dependency>
    <groupId>org.apache.parquet</groupId>
    <artifactId>parquet-avro</artifactId>
    <version>1.10.0</version>
</dependency>

 

 

But how can I avoid this in the future? I had to add parquet-avro, because without there were some errors. Do I have to lookup such conflicts manually and then choose the same version like at flink dependencies ?

 

 

Best,

Jan

Hi Jan,

 

it looks to me that you might have different parquet-avro dependencies on your class path. Could you make sure that you don't have different versions of the library on your classpath?

Till

Hi at all,

 

i’m using Flink 1.11 with the datastream api. I would like to write my results in parquet format into HDFS.

 

Therefore i generated an Avro SpecificRecord with the avro-maven-plugin:

<plugin>
                <groupId>org.apache.avro</groupId>
                <artifactId>avro-maven-plugin</artifactId>
                <version>1.8.2</version>

                        </configuration>
                    </execution>
                </executions>
            </plugin>

 

 

Then  I’m using the SpecificRecord in the StreamingFileSink:

val sink: StreamingFileSink[SpecificRecord] = StreamingFileSink
  .forBulkFormat(
    new Path("hdfs://example.com:8020/data/"),
    ParquetAvroWriters.forSpecificRecord(classOf[SpecificRecord])
  )
  .build()

 

 

The job cancels with the following error:

Another strategy to resolve such issues is by explicitly excluding the conflicting dependency from one of the transitive dependencies.

Besides that, I don't think there's a nicer solution here.
