Ted Yu commented on HBASE-7006:
-------------------------------
for concern #1, step 2 (log replay) implies the crash of original region server.
In step 3, how would C carry timestamp 0 which is the same as A and B ?

> 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.
