Subject [jira] [Commented] (HBASE-6053) Enhance TestRegionRebalancing test to be a system test
Date Thu, 31 May 2012 05:36:23 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13286339#comment-13286339

stack commented on HBASE-6053:

We already have a fundamental class named ServerManager.  See in master package.  Naming your
new class ServerManager will cause confusion.

Why we need ServerManager at all? What does it add that is not in our wrapper scripts starting
and stopping servers?  (Why do control up in java rather than in shell scripts w/ easier access
to ssh and the shell commands this java script depends on?

The change to TestRegionRebalancing looks good making it a Tool

Whats going on here?

Are you going to hunt all system properties for those named w/ a proc_ prefix?

There seems to be a stray { in the line you add above.
