Subject [jira] Commented: (HBASE-1018) Regionservers should report detailed health to master; master should flag troubled regionservers in UI
Date Tue, 25 Nov 2008 21:58:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650762#action_12650762

stack commented on HBASE-1018:
------------------------------

+1 on removing TTS (I've been burned by its sillyness too often to admit).

One thought I had -- don't have to do it here, we can do it later -- is that the heartbeat
should carry the data portion of RegionServerMetrics .... or you'd stuff a RSM into a ServerLoad
and it would know how to iterate over all Metrics in RSM and extract current value.  We'd
do this so just adding to the RSM would have the new metric show master-side. 

Otherwise, +1 on this patch as is.

> Regionservers should report detailed health to master. The master should flag troubled
regionservers in the UI.
> The concern at the moment is primarily heap. Regionservers should report used, committed,
and max heap metrics in the periodic report. The master should flag in the regionserver list
on /master.jsp those regionservers where available heap is below a configurable threshold.
