Subject [jira] [Created] (HADOOP-9546) "setsid exited with exit code" message on each hadoop command
Date Mon, 06 May 2013 20:16:17 GMT
Jason Lowe created HADOOP-9546:
----------------------------------

             Summary: "setsid exited with exit code" message on each hadoop command
                 Key: HADOOP-9546
                 URL: https://issues.apache.org/jira/browse/HADOOP-9546
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Jason Lowe


Each hadoop command is printing an INFO message about a setsid exit code.  This is at best
annoying, and it prevents the start-dfs.sh startup script from working properly since the
INFO message is interpreted as more namenode hosts to connect to.  start-dfs.sh uses {{hdfs
getconf -namenodes}} which like other hadoop commands prints the extra INFO message.  For
example:

{noformat}
$ hdfs getconf -namenodes
2013-05-06 20:11:22,096 INFO  [main] util.Shell (Shell.java:isSetsidSupported(311)) - setsid
exited with exit code 0
localhost
{noformat}
