Re: [VOTE] The 2nd hbase 0.94.14 release candidate is available for download

Similar dance as the last time:

- downloaded tarballs, both passed md5 and asc verification. [✓]
- load 10m rows/host into a 0.94.6.1 secured cluster (sequentialWrite
--nomapred), launch randomRead (--nomapred) test.
- deployed 0.94.14 jars over existing 0.94.6.1 regionservers, restart one
by one. [✓]
- new job launched from 0.94.6.1 "gateway" host, with older jars installed
(randomRead, mapreduce). [✓]
- deployed 0.94.13 jars over existing 0.94.6.1 master, restart. [✓]
- manually split test table while job running. [✓]

I noticed that it took a little while for the RS's to open regions and
start serving requests once it came back online after the upgrade. I didn't
record stats the last time I did this and didn't log events that closely
this time either, so I don't have anything concrete for comparison. It just
seemed slower than perhaps it should. No errors in the logs either, so
*shrug*

+1.
