Subject [jira] Resolved: (HBASE-730) On startup, rinse STARTCODE and SERVER from .META.
Date Thu, 10 Jul 2008 17:46:33 GMT

     [ https://issues.apache.org/jira/browse/HBASE-730?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack resolved HBASE-730.
-------------------------

    Resolution: Fixed

Committed.  Thanks J-D.

We're not actually rinsing SERVER and STARTCODE -- its hard to do for .META. case as J-D states
above -- but this patch seems to get the same effect by forcing the first scan.

> Look into what it would take purging startcode and server from .META. on startup.  It
might make startup run faster.  In particular, Clint Morgan was asking for faster startup.
 Below is from a reply.  The +1 is from JK.
