Subject [jira] Commented: (HBASE-546) Use Zookeeper in HBase
Date Wed, 11 Jun 2008 20:20:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12604324#action_12604324

Jean-Daniel Cryans commented on HBASE-546:

Completely  overlooked something. This solution misses the fact that if we want to start the
processes with start-hbase.sh we need a file with the zk servers in it (like st^ack was saying
on IRC, I just woke up). So it means having to duplicate the information. But, if ZK cluster
is for more than just HBase usage, leaving  the zkservers file blank would enable this really

> Zookeeper =~ Chubby. This means that we could take advantage of a distributed lock manager
to coordinate things like failover masters, regionservers staying online when master is dead,
atomic region->regionserver assignments, etc. There are a lot of opportunities for improvements
here. Please add discussions of particular features in comments or sub-tasks.
