stack commented on HBASE-698:
-----------------------------

HBASE-1439 is talking about ownership of commit logs being orchestrated by zk; perhaps on startup (or on assumption of master role) master can check zk if commit logs to replay.

> HLog recovery is not performed after master failure

>          Issue Type: Bug
>          Components: master, regionserver
>    Affects Versions: 0.1.2

>            Priority: Blocker

> I have a local cluster running, and its logging to
> <hbase>/log_X.X.X.X_1213228101021_60020/
> Then I kill both master and regionserver, and restart. Looking through
> the logs I don't see anything about trying to recover from this hlog,
> it just creates a new hlog alongside the existing one (with a new
> startcode).  The older hlog seems to be ignored, and the tables
> created in the inital session are all gone.
