Subject [jira] [Commented] (HDFS-6956) Allow dynamically changing the tracing level in Hadoop servers
Date Sun, 21 Sep 2014 23:09:34 GMT

Masatake Iwasaki commented on HDFS-6956:
----------------------------------------

lgtm. I tried the patch in pseudo-distributed cluster and it worked. 
It would be helpful to show INFO message in server log when span receiver is removed.

> We should allow users to dynamically change the tracing level in Hadoop servers.  The
easiest way to do this is probably to have an RPC accessible only to the superuser that changes
tracing settings.  This would allow us to turn on and off tracing on the NameNode, DataNode,
etc. at runtime.
