> Key: BEAM-11231
> URL: https://issues.apache.org/jira/browse/BEAM-11231
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp, io-java-hadoop-file-system,
> io-java-hadoop-format, io-java-hbase, runner-dataflow
> Affects Versions: 2.24.0
> Reporter: Cheng Li
> Priority: P2
> Labels: GCP, stale-P2
>
> Current(as of Beam SDK 2.24.0) Java Dataflow workers does not ship with
> [Hadoop native
> library|https://hadoop.apache.org/docs/r2.8.5/hadoop-project-dist/hadoop-common/NativeLibraries.html]
> and popular native compression codecs(e.g libsnappy) .
> If one try to read files using IO classes that assume native library
> support(e.g, org.apache.hadoop.hbase.mapreduce.TableSnapshotInputFormat) on
> GCP Dataflow, the following error will be throw if the file is compressed by
> snappy:
>
> {code}
> java.io.IOException: Failed to start reading from source:
> org.apache.beam.sdk.io.hadoop.format.HadoopFormatIO$HadoopInputFor
> matBoundedSource@311fa603
> ...
> Caused by: org.apache.hadoop.hbase.DoNotRetryIOException:
> java.lang.RuntimeException: native snappy library not available: this version
> of libhadoop was built without snappy support.
>
> {code}
> There is very little one can do from within pipeline job code unless
> rewriting the IO class, so it might make sense to include these native
> libraries for Hadoop IOs
