Lars Hofhansl resolved HBASE-7077. ---------------------------------- Resolution: Fixed Committed to 0.94 and 0.96. Thanks for the nice test Ram. (I change the test name to TestHBase7051) > Test for: CheckAndPut should properly read MVCC > ----------------------------------------------- > > Key: HBASE-7077 > URL: https://issues.apache.org/jira/browse/HBASE-7077 > Project: HBase > Issue Type: Sub-task > Reporter: Gregory Chanan > Fix For: 0.94.3, 0.96.0 > > Attachments: HBASE-7071.patch, HBASE-7071_testcasewithassert.patch > > > checkAndPut should integrate with MVCC, similar to how HBASE-4583 fixed > appends and increments. > Also need a test, here's one we could use (originally proposed in HBASE-7051): > The current value of some cell is 10. > I issue two concurrent requests: > A) a check and put where check value = 10, put value = 11 > B) a put where put value = 50 > The only result at the end of these operations that seems reasonable to me is > the value of the cell being 50. If A occurred first (ACID wise), then our > values go 10->11->50. If B occurred first, then our values go 10->50 (and the > checkAndPut fails) -- This message is automatically generated by JIRA.
