Subject [jira] Commented: (HIVE-551) Metrics for Hive
Date Fri, 24 Jul 2009 20:23:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12735146#action_12735146

Edward Capriolo commented on HIVE-551:

Saw something JMX related in another Jira and wanted to bring this up

Suppose we had a configuration option like...
set hive.jmx.server.per.job=true
set hive.jmx.server.user=ed
set hive.jmx.server.password=ed

A hive query would emit a status line like...
jmx url = service:///jmx/hostname:port

Different types of queries would be free to add objects to the MBean server and then someone
could attach in and profile a job as running.

FilesScanned, the challenge here is that multiple instanced of hive could be running, hive
server,hive cli, hivecli so having a dedicated JMX port like in the configuration file would
be difficult. The user could set the JMX port through the CLI. Any thoughts?
