Subject [jira] [Commented] (HBASE-14314) Metrics for block cache should take region replicas into account
Date Wed, 09 Sep 2015 20:18:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14737511#comment-14737511

Enis Soztutar commented on HBASE-14314:
---------------------------------------

bq. Can we do the above in another JIRA ?
We can. It is a question of whether L1 / L2 breakdown will be also this way. I say we should
try the suggested approach, and not cut corners when L1 breakdown is added.

> Currently metrics for block cache are aggregates in the sense that they don't distinguish
primary from secondary / tertiary replicas.
> This JIRA separates the block cache metrics for primary region replica from the aggregate.
