> Support hadoop < 2.7 with StreamingFileSink.BulkFormatBuilder

> Key: FLINK-14170
> URL: https://issues.apache.org/jira/browse/FLINK-14170
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / FileSystem
> Affects Versions: 1.8.0, 1.8.1, 1.8.2, 1.9.0
> Reporter: Bhagavan
> Priority: Major
>
> Currently, StreamingFileSink is supported only with Hadoop >= 2.7
> irrespective of Row/bulk format builder. This restriction is due to truncate
> is not supported in Hadoop < 2.7
> However, BulkFormatBuilder does not use truncate method to restore the file.
> So the restricting StreamingFileSink.BulkFormatBuilder to be used only with
> Hadoop >= 2.7 is not necessary.
> So requested improvement is to remove the precondition on
> HadoopRecoverableWriter and allow BulkFormatBuilder (Parquet) to be used in
> Hadoop 2.6 ( Most of the enterprises still on CDH 5.x)
>
