Subject [jira] [Commented] (HIVE-13145) Separate the output path of metrics file of HS2 and HMS
Date Mon, 29 Feb 2016 18:43:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15172343#comment-15172343

Szehon Ho commented on HIVE-13145:
----------------------------------

Thanks for the patch.  Can I ask what problem it tries to solve?  I'm not against to the patch,
but just wanted to see if there are already some solutions.

I thought initially that if HMS and HS2 are separate processes on same machine, then you can
configure both to have a different hive-site and thus different metrics-file location.  If
it is embedded mode and they are both the same process, then both are written to same file,
which doesn't seem a problem to me?

> The output path of  metrics file of HS2 and HMS can define by {{hive.service.metrics.file.location}}
property at present.
> When it starts HS2 and HMS by the same server, both metrics is written in the same file.
And when confirming this file, it is difficult to judge which metrics it is.
> Therefore the output path of metrics file of HS2 and HMS is separated.
