Subject [jira] [Commented] (HBASE-12361) Show data locality of region in table page
Date Wed, 29 Oct 2014 02:56:33 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14187925#comment-14187925

Liu Shaohui commented on HBASE-12361:
-------------------------------------

[~apurtell]
We only exposed the locality metrics named hdfsBlocksLocalityIndex which is for regionserver,
not for region.
Data locality for region is more important to analysis the performance after region movment
for balance, regionserver failover and so on.

The reason why i'd like to show it in the UI is it's more direct for later performance tuning
and more attentions will be paid on this metrics.
