[jira] Updated: (ZOOKEEPER-483) ZK fataled on me, and ugly
[ https://issues.apache.org/jira/browse/ZOOKEEPER-483?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] ryan rawson updated ZOOKEEPER-483: -- Attachment: zklogs.tar.gz here is the complete log set from all 5 of our quorum members for the entire day. note that the event happens around 12:30 pm local (PDT) time in the log. I restarted the 3 crashed machines at about 13:30. They were not run under supervision, but clearly they should. The machines in question only have 1 disk, since they also run other hadoop things, and I was hoping that the quorum model would provide reliability even if the local disk isnt 100%. Although, having said that, the local disk seems to be ok, since nothing else on them has died.

This was opened as ZOOKEEPER-457. I think the problem might have happened when someone ran a heavy duty map-reduce with a major pile of disk IO intermediate output, which may have delayed zookeeper log writes.

[jira] Updated: (ZOOKEEPER-457) Make ZookeeperMain public, support for HBase (and other) embedded clients

This will allow our users to use 1 shell to manipulate both hbase things and zookeeper things. It requires making a few things public, and in the process rearranging how some static things are initialized. It's fairly trivial refactoring, hopefully you guys approve!
