Subject [jira] [Created] (HADOOP-14369) NetworkTopology calls expensive toString() when debugging
Date Mon, 01 May 2017 23:21:04 GMT
Inigo Goiri created HADOOP-14369:
------------------------------------

             Summary: NetworkTopology calls expensive toString() when debugging
                 Key: HADOOP-14369
                 URL: https://issues.apache.org/jira/browse/HADOOP-14369
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Inigo Goiri
            Assignee: Inigo Goiri


When {{NetworkTopology}} calls {{add()}} or {{remove()}}, it calls {{toString()}} for {{LOG.debug()}}
which is pretty expensive.
