Calvin Qu commented on HBASE-8676:
----------------------------------
Hi Lars,the data can be included in major compaction not in minor compaction.If
not,what does hbase.hstore.compaction.max.size mean?
I hava tried to add conf hbase.hstore.compaction.max in hbase-site.xml with
value 10 or 5,but the larger file also is included.
another example,
hfile1 t1 10G
hfile2 t2 100G
hfile3 t3 1G
hfile4 t4 100G
t1-->t4(older-->newer),no big file will be excluded.
> hbase.hstore.compaction.max.size parameter has no effect in minor compaction
