[jira] [Commented] (CASSANDRA-3992) Add setloglevel command to Cli to call setLog4jLevel JMX method

["Brandon Williams (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-3992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13221637#comment-13221637 ] 

Brandon Williams commented on CASSANDRA-3992:
---------------------------------------------

I can see how this would seem handy for development, but really it's less powerful than changing log4j-server.properties since it's all or nothing - you can't set a specific class/package to DEBUG, for instance.  I haven't tested this in a while, but if you edit the log4j file Cassandra should re-read it after a few seconds and enact the changes.
