Subject [jira] [Commented] (HIVE-17307) Change the metastore to not use the metrics code in hive/common
Date Sat, 12 Aug 2017 19:53:01 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16124696#comment-16124696

Alan Gates commented on HIVE-17307:
-----------------------------------

I propose that we move the metastore to use the codahale metrics directly.  The reason that
the current Metrics interface was created was to allow the legacy metrics system to co-exist
with the new codahale metrics.  As far as I know Yahoo was the only user of the legacy metrics
system.  I have spoken to [~mithun] and [~cdrome] and they are fine with not continuing support
for the legacy metrics in the standalone metastore.  Removing the Metrics interface and using
codahale metrics directly is a much simpler solution.

> As we move code into the standalone metastore module, it cannot use the metrics in hive-common.
 We could copy the current Metrics interface or we could change the metastore code to directly
use codahale metrics.
