Anoop Sam John commented on HBASE-14970:
----------------------------------------
One point to be checked.
Now we have a Chore Service thread running per region which by default checks
for possible clean up (of compacted away HFiles) in every 2 mins. Now we have a
thread pool in HStore level (with chore threads= 10) and close of each file is
handled by one thread. DO we really need these many threads in the system?
The max possible #compacted away files per region, can it be handled by that
same chore service thread ?
If we have 100 regions and 2 CFs per region, then we will have 200*10 = 2000
threads??
> Backport HBASE-13082 and its sub-jira to branch-1
