Recently we copied a table form Production to UAT using Copy table utility, table size is identical with Production when copy completed. After some time size keep growing by 300%. its actual size of table not WAL.

Original size  -

891.6 G  1.7 T    /hbase/data/default/PC.MESSAGES.RFPVD.UATBASE.221130

Now(after 3 days), it is changed to -

3.3 T    6.6 T    /hbase/data/default/PC.MESSAGES.RFPVD.UATBASE.221130

did all the validations and comparisons with source files about compression and compaction etc.
