Subject [jira] [Created] (HBASE-7057) Store Server Load in a Table
Date Fri, 26 Oct 2012 17:47:12 GMT
Elliott Clark created HBASE-7057:
------------------------------------

             Summary: Store Server Load in a Table
                 Key: HBASE-7057
                 URL: https://issues.apache.org/jira/browse/HBASE-7057
             Project: HBase
          Issue Type: Improvement
          Components: metrics, UI
    Affects Versions: 0.96.0
            Reporter: Elliott Clark
             Fix For: 0.98.0


Currently the server hart beat sends over server load and region loads.  This is used to display
and store metrics about a region server.  It is also used to remember the sequence id of flushes.

This should be moved into an HBase table.  

* Allow the last sequence id to persist over a master restart.
* That would allow the balancer to have a more complete picture of what's happened in the
past.
* Allow tools to be created to monitor hbase using hbase.
* Simplify/remove the heartbeat.
