Subject [jira] Commented: (HBASE-1502) Remove need for heartbeats in HBase
Date Wed, 01 Sep 2010 05:34:53 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12904924#action_12904924

Jonathan Gray commented on HBASE-1502:

Following HBASE-2692, I think the only thing we're really using the heartbeat for is the mostLoaded
servers.  But we're actually tracking all assignment in-memory anyways, so maybe we can do
this now?  Shutdown stuff could come on it's own RPC?

> HBase currently uses heartbeats between region servers and the master, piggybacking information
on them when it can. This issue is to investigate if we can get rid of the need for those
using ZooKeeper events.
