Subject Re: [VOTE] First release candidate for HBase 1.1.0 (RC0) is available.
Date Mon, 11 May 2015 18:40:43 GMT
Finally, from my side:

- verified public keys vs both ndimiduk.asc and KEY files
- verified build against hadoop versions (2.3.0 2.4.0 2.4.1 2.5.0 2.5.1
2.5.2 2.6.0 2.7.0), with both java-1.7.0-openjdk- and
java-1.8.0-openjdk- Acknowledged 2.2 issue
via HBASE-13637
- run LoadTestTool against standalone cluster built from src tar ball with
FAST_DIFF block encoder and ROWCOL blooms. No issues, logs look good.
- on 7-node cluster, verified rolling upgrade from 0.98.0 while
concurrently running LoadTestTool with LZ4 compression (0.98.0 client). No
issues, logs look good.
- run IntegrationTestBigLinkedList with slow deterministic CM on 6-node
cluster for 24+ hours. All chains verified.

I'm +1 on the bits in this release. However, there are enough minor issues
now accumulated that I think it's worth while spinning a new RC. I propose
an RC1 which contains only the following patches over RC0:
 - HBASE-13637 (Hadoop-2.2 compilation issue)
 - HBASE-13661 (Enis's InterfaceAudience find)
 - a resolution to the RegionScanner interface change, if deemed necessary
 - corrected docs and site build

Since this RC has already been open for 12 days and that RC would contain
an extremely limited set of changes above RC0, I would like to run it
through an abbreviated voting window -- say 48 hours.
