Subject manually splitting Hlogs
Date Sat, 14 Apr 2012 16:49:25 GMT
Hello all,

We had a node die on us, and the master could not recover the HLogs due to timeout issues,
but HBase stayed up and all of the regions were re-assigned. The node crashed hard (IT is
investigating why) so we were not able to just restart it.

I looked into org.apache.hadoop.hbase.regionserver.wal.HLog --split  and didn't see any notes
about not running on a live cluster so I ran it and it ran fine.  Was it safe to run with
hbase up? Were the newly created files correctly added to the existing regions?
