[VOTE] The 2nd hbase 0.94.12 release candidate is available for download
The 2nd 0.94.12 RC is available for download at http://people.apache.org/~larsh/hbase-0.94.12-rc1/
Signed with my code signing key: C7CFE328

As before 0.94.12 is mostly a bug fix release and has 38 issues resolved against it:
    [HBASE-9277] - REST should use listTableNames to list tables
    [HBASE-9279] - Thrift should use listTableNames to list tables
    [HBASE-7709] - Infinite loop possible in Master/Master replication
    [HBASE-7954] - Fix the retrying logic of memstore flushes to avoid extra sleep
    [HBASE-8760] - possible loss of data in snapshot taken after region split
    [HBASE-8930] - Filter evaluates KVs outside requested columns
    [HBASE-9167] - ServerCallable retries just once if timeout is not integer.max

Please try out the RC, check out the doc, take it for a spin, etc, and vote +1/-1 by September 30th on whether we should release this as 0.94.12.
