Subject [jira] [Updated] (HBASE-4300) Start of new-version master fails if old master's znode is hanging around
Date Thu, 15 Sep 2011 17:26:09 GMT

     [ https://issues.apache.org/jira/browse/HBASE-4300?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack updated HBASE-4300:

    Attachment: 4300.txt

Add new static parseServerName method to ServerName.  It tests the passed String to see if
it matches the ServerName pattern, if not, it tries to treat the string as "<hostname>
':' <port>".  Replaced all places where we get raw 'new ServerName' instances that take
raw zk bytes with this new parseServerName method.

One day should protobuf/json it all.  Would need to allow for the binary preamble all data
has since we added in RecoverableZookeeper.

> I shut down an 0.90 cluster, and had to do so uncleanly. I then started a trunk (0.92)
cluster before the old master znode had expired. This cased:
