Subject [jira] [Commented] (HBASE-4057) Implement HBase version of "show processlist"
Date Fri, 08 Jul 2011 21:59:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4057?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13062216#comment-13062216

Nicolas Spiegelberg commented on HBASE-4057:

@Andrew : we're trying to figure out the best way to expose this data.  Perceived options:

1. Write a Java utility and expose via bin/hbase
2. Put into Ruby shell
3. HTTP-get

One of the complaints that our operations developers had was being forced to use Ruby for
scripting if they go through the shell (they are mostly Python), so integrating that isn't
a high pri for us.  I was thinking the benefit of using HTTP-get over Java util is that we
don't have to design a public RPC interface, but maybe RPC is the best solution.

> One of the features that our DBAs use for MySQL analysis is "show processlist", which
gives application-level stats about the RPC threads.  Right now, we use jstack but that is
very core-developer-centric.  We need to create a similar tool that DBA/Ops/AppDevs can use.
