Subject [jira] [Commented] (HBASE-13213) Split out locality metrics among primary and secondary region
Date Wed, 11 Mar 2015 22:19:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14357712#comment-14357712

Ted Yu commented on HBASE-13213:
--------------------------------

Here is result of preliminary testing:
Verified that some regions of IntegrationTestTimeBoundedRequestsWithRegionReplicas table have
replica Id of 1 or 2 using http://xx:16030/rs-status
{code}
IntegrationTestTimeBoundedRequestsWithRegionReplicas,b999998e,1425341957962_0002.c0be8d17b9183aa1f6a1c305a5a527cd.
b999998e	bffffff4	2
IntegrationTestTimeBoundedRequestsWithRegionReplicas,c666665a,1425341957962_0002.5ebffccd8800b48fe62939250b6bb8db.
c666665a	ccccccc0	2
{code}
Using http://xx:16030/jmx, verified that locality for secondary regions has some value:
{code}
 "percentFilesLocal" : 25,
    "percentFilesLocalSecondaryRegions" : 45,
{code}

> This task provides the ability to track locality of primary and secondary region replicas.
> We already have percentFilesLocal metric.
> There should be two sets of metrics - one for primaries and another for secondary / tertiary
regions.
