Subject [jira] [Created] (YARN-3350) YARN RackResolver spams logs with messages at info level
Date Mon, 16 Mar 2015 03:42:38 GMT
Wilfred Spiegelenburg created YARN-3350:
-------------------------------------------

             Summary: YARN RackResolver spams logs with messages at info level
                 Key: YARN-3350
                 URL: https://issues.apache.org/jira/browse/YARN-3350
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 2.6.0
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg


When you run an application the container logs shows a lot of messages for the RackResolver:

2015-03-10 00:58:30,483 INFO [RMCommunicator Allocator] org.apache.hadoop.yarn.util.RackResolver:
Resolved node175.example.com to /rack15

A real world example for a large job was generating 20+ messages in 2 milliseconds during
a sustained period of time flooding the logs causing the node to run out of disk space.
