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}
