Jason Lowe created HDFS-4427:
--------------------------------
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

(NativeCodeLoader.java:<clinit>(62)) - Unable to load native-hadoop library for
your platform... using builtin-java classes where applicable
