mahua updated HBASE-27537:
--------------------------
Description:
Although table has a TTL set in the cluster，some regions do not perform
periodic major compactions，and the expired TTL data is still stored in these
large files. Not trigger the reason is that the periodic check of the thread
according to number of files in the region If > hbase.hstore.compaction.min
then major compaction is not triggered, Instead, minor compaction is triggered
first. But minor compaction which excludes large files (by the
hbase.hstore.compaction.max.size), when the larger files reach a certain
number, the expired data under the larger files cannot be deleted normally.
