> Key: HDFS-6956
> URL: https://issues.apache.org/jira/browse/HDFS-6956
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode, namenode
> Affects Versions: 2.6.0
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe

>
> 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.
