> The issue aims to verfiy FLINK-29635.
> Please verify in batch mode, the document is in
> [https://nightlies.apache.org/flink/flink-docs-master/docs/connectors/table/hive/hive_read_write/#file-compaction]:
>
> 1: enable auto-compaction, write some data to a Hive table which results in
> the average size of files is less than compaction.small-files.avg-size(16MB
> by default), verfiy these files should be merged.
> 2: enable auto-compaction, set compaction.small-files.avg-size to a smaller
> values, then write some data to a Hive table which results in the average
> size of files is greater thant the compaction.small-files.avg-size, verfiy
> these files shouldn't be merged.
> 3. set sink.parallelism manually, check the parallelism of the compact
> operator is equal to sink.parallelism.
> 4. set compaction.parallelism manually, check the parallelism of the compact
> operator is equal to compaction.parallelism.
> 5. set compaction.file-size, check the size of the each target file merged is
> about the `compaction.file-size`.
>
> We shoud verify it with writing non-partitioned table, static partition
> table, dynamic partition table.
> We can find the example sql for how to create & write hive table in the
> codebase
