Brad Anderson commented on HBASE-3900:
--------------------------------------
I've done a bit of work on this here:
https://github.com/boorad/hbase/commit/51cdcb14680275a74a949a79b5f9b27c844be11c
It's my first patch for hbase, so feedback is welcome.
Talking with stack in irc, and he expressed a desire to see the compaction
queue (ordered) with an identifier & whether or not it is a major compaction.
I left this out of the above patch, as I am planning on reworking the existing
web ui to be a bit friendlier to devs and ops folks.
> Expose progress of a major compaction in UI and/or in shell

> Issue Type: Task
> Reporter: stack
>
> A general recommendation is to turn off major compactions and run them
> externally only currently the only way to follow progress of a major
> compaction is by study of regionserver logs. Add a feature that gives a
> percentage complete of major compaction up in the UI or in shell.
