Jean-Daniel Cryans updated HBASE-698:
-------------------------------------
Attachment: hbase-698-0.19.patch
Patch against 0.19 branch. It will recover any log directory found at the root
HBase folder. I tried it on my machine by creating a table, inserting 500 rows
into it and then killing --9 both Master and RS. After restart everything was
there. This patch doesn't cover the situation where the logs weren't flush to
disk (inserting 10 rows didn't trigger it) and it doesn't take into account
existing RS like the patch for trunk does.
> HLog recovery is not performed after master failure

> 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.
