Anoop Sam John commented on HBASE-15055:
----------------------------------------
bq.In the current code, it seems the skipLargeFiles() is possibly not called if
'forceMajor' is true.
Yes. But this flag is on for explicit major compaction calls from user. I
mean the system made major compaction after the configured interval. That
check for whether this can be a major one is after this step of skipLargeFiles.
Regarding ExploringCompactionPolicy, I too noticed and also saw this issue
already been raised. See HBASE-14409.
We need some cleanup.
> Major compaction is not triggered when both of TTL and

> Some large files may be skipped by hbase.hstore.compaction.max.size in
> candidate selection. It causes skipping of major compaction. So the TTL
> expired records are still remained in the disks and keep consuming disks.
> To resolve this issue, I suggest that to skip large files only if there is no
> TTL expired record.
