Subject [jira] Commented: (HBASE-1502) Remove need for heartbeats in HBase
Date Wed, 08 Dec 2010 00:08:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12969083#action_12969083
] 

Jonathan Gray commented on HBASE-1502:
--------------------------------------

We're also using the regionServerStartup or regionServerReport to determine an RS is online
(we use the ZK node to determine when it dies).  This stuff would also need some cleanup/rework
to completely drop heartbeats.

> 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.
