Jonathan Gray commented on HBASE-1058:
--------------------------------------

Have not tested, but patch looks good.  +1 for commit.

We can still debate about whether to get rid of this behavior, but in my testing on my small cluster on trunk, this prevented my cluster from being hosed under heavy stress by bringing up the update wall when we start to overrun compactions (post HBASE-1618).

> A rabid upload will easily outrun our compaction ability dropping flushes faster than we can compact them up.  Fix.
