Subject [jira] [Commented] (HBASE-5790) ZKUtil deleteRecursively should be a recoverable operation
Date Wed, 18 Apr 2012 06:34:29 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5790?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13256243#comment-13256243
] 

Jesse Yates commented on HBASE-5790:
------------------------------------

Looks like the tests pass on that QA run, but I guess its angry about the second stage (related
to keywals's recent comments on dev?). Here is the output line from the console:
{quote}
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12-TRUNK-HBASE-2:test
(secondPartTestsExecution) on project hbase: Failure or timeout
{quote}
Is there an easy way to see which findbugs warnings were introduced? I figure since we are
tracking them correctly, we should have a way to say what they are, but I couldn't see a way
to do it besides checking against a good run and that is a huge pain...

> As of 3.4.3 Zookeeper now has full, multi-operation transaction. This means we can wholesale
delete chunks of the zk tree and ensure that we don't have any pesky recursive delete issues
where we delete the children of a node, but then a child joins before deletion of the parent.
Even without transactions, this should be the behavior, but it is possible to make it much
cleaner now that we have this new feature in zk.
