Jeffrey Zhong commented on HBASE-7006:
--------------------------------------
@Ted,
Yes, my first patch will include major logic for this JIRA and will be attached
to a sub task JIRA(to be created) and be submitted within these two days. There
will be two more sub JIRAs: one is to create a replay command and the other is
to add metrics for better reporting purpose.
Thanks,
-Jeffrey

> 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.
