--------------------------------

             Summary: start-dfs.sh generates malformed ssh command when not running with native libs
                 Key: HDFS-4427
                 URL: https://issues.apache.org/jira/browse/HDFS-4427
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: scripts
            Reporter: Jason Lowe


After HADOOP-8712 the start-dfs.sh script is generating malformed ssh commands when the native hadoop libraries are not present.  This is because {{hdfs getconf}} is printing a warning, and that warning is accidentally interpreted as one of the machines to target for ssh.

Here's an example output of hdfs getconf:

{noformat}
$ hdfs getconf -namenodes 2>/dev/null
2013-01-22 21:03:59,543 WARN  util.NativeCodeLoader (NativeCodeLoader.java:<clinit>(62)) - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
