stack commented on HBASE-7006:
------------------------------

I added note to refguide that folks should run w/ newer zks and point to 
ZOOKEEPER-1277 as a justification.

> Just saw interesting issue where a cluster went down  hard and 30 nodes had 
> 1700 WALs to replay.  Replay took almost an hour.  It looks like it could run 
> faster that much of the time is spent zk'ing and nn'ing.
> Putting in 0.96 so it gets a look at least.  Can always punt.
