Subject [jira] Commented: (HBASE-730) On startup, rinse STARTCODE and SERVER from .META.
Date Tue, 08 Jul 2008 21:52:31 GMT

    [ https://issues.apache.org/jira/browse/HBASE-730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12611819#action_12611819

stack commented on HBASE-730:
-----------------------------

On current patch:

Perhaps make an accessor rather than change the following to be protected?  +  protected final
Sleeper sleeper;

Why have a nextPeriod?  Why not just have a setPeriod?

Otherwise, good so far J-D.

> 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.
