Subject Re: [VOTE] Second release candidate for HBase 1.1.0 (RC1) is available.
Date Tue, 12 May 2015 06:15:09 GMT
Here's my review and +1:

[✓] verified tarballs vs public key in p.a.o/keys/committers/ndimiduk.asc.
[✓] extracted src tgz, structure looks good.
[✓] verified build of src tgz against hadoop versions (2.2.0/minikdc=2.3.0,
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
jdk1.7.0_67.jdk (mac) and jdk1.8.0_20.jdk (mac).
[✓] run LoadTestTool against standalone built from src tgz with FAST_DIFF
block encoder and ROWCOL blooms. No issues, logs look good.
[✓] poked around with the shell on the same: list, status, snapshot,
compact, drop, clone, delete_snapshot, drop. no issues, logs look good.
[✓] built site from src tgz. site and book looks good.
[✓] extracted bin tgz, inspect structure. look good.
[✓] started standalone from bin tgz, poked webUI, dumped metrics, conf,
"debug". looks good.
[✓] load the site from bin tgz. noticed issue with non-relative link, filed
[✓] ran Stack's hbase-downstreamer [0] vs. the maven repo. tests pass.
[✓] inspected compatibility reports vs. 0.98.0 [1] (skimmed) and 1.0.0 [2]
(thoroughly, comment on HBASE-13661). Looks okay to me.

Additionally, against RC0 I did the following:

[✓] 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, 15 loops of 75mm. All chains verified.
