Subject [jira] [Updated] (HBASE-1502) Remove need for heartbeats in HBase
Date Thu, 28 Apr 2011 06:01:05 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1502?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-1502:
-------------------------

      Resolution: Fixed
    Release Note: Deprecates what were once considered fundamental classes, HServerInfo and
HServerAddress.  The former has been made irrelevant because its constituent info -- server
name, server load -- is now passed otherwise. HServerAddress, a class that on deserialization,
did a resolve (it created a new InetSocketAddress on deserialization) was just a bad idea
from the get-go.  Unfortunately, HSI and HSA were all over our codebase like a cancer.  Hopefully
the patient survives their purging.
    Hadoop Flags: [Reviewed]
          Status: Resolved  (was: Patch Available)

Committed to trunk (Sorry for test breakage -- I'm on it.  Sorry for making so big a patch.
 Won't do it again).

> 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.
