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.

> 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.
