> hbase bulkload (HFileOutputFormat2) generate hfile ,the compression from the table(cf) compression,
> if the compression can be set on client ,sometimes,it's useful,
> some case in our production:
> 1、hfile bulkload replication between the data center with bandwidth limit, we can set the compression of the bulkload hfile not changing the table compression
> 2、bulkload hfile not set compression ,but the table compression is gz/zstd/snappy... ,can reduce the hfile created time and compaction will make the hfile to compression finally
> 3、somethings the yarn nodes (hfile created by reduce) /dobulkload client has no compression lib,but the hbase cluster has,it's useful for this case
