Subject Re: ANN: The fourth hbase 0.92.0 release candidate is available for download
Date Sat, 14 Jan 2012 01:10:04 GMT

I've been testing this under heavy write loads and I also looked at
replication. On previous RCs I did many read tests and AFAIK that
didn't change so I didn't go through that again. I think this is a
solid release, and 0.92.1 will take care of bugs that didn't make it
in time.
