Subject Re: VOTE: hbase-0.95RC1, the second "Development" Series Release is available [WAS -> VOTE: hbase-0.95.0RC0, the first "Developer Release" release candidate is available for download and vote]
Date Sat, 06 Apr 2013 05:31:44 GMT
Installed the -hadoop1 tarball, started HBase, inserted some data, flushed, compacted, scanned,
inspected the UI pages, stopped it again.
Checked the docs.

CHANGES.txt is a bit weird as it does not contain the 0.94 issues from before it was branched,
but that's just a nit.

In the logs I see:
2013-04-05 22:18:03,805 WARN org.apache.hadoop.hbase.regionserver.HRegionServer:

Caused by: org.apache.hadoop.hbase.exceptions.ServerNotRunningYetException: org.

But in the end the RS started up anyway. Again, just a nit (in local mode the master does
not start fast enough it seems, and the RS is too impatient).

Any chance of a few more +1s here so I can push this out?  Thanks all.
