Subject [jira] [Created] (YARN-1168) Cannot run "echo \"Hello World\""
Date Sat, 07 Sep 2013 06:39:52 GMT
Tassapol Athiapinya created YARN-1168:
-----------------------------------------

             Summary: Cannot run "echo \"Hello World\""
                 Key: YARN-1168
                 URL: https://issues.apache.org/jira/browse/YARN-1168
             Project: Hadoop YARN
          Issue Type: Bug
          Components: applications/distributed-shell
            Reporter: Tassapol Athiapinya
            Priority: Critical
             Fix For: 2.1.1-beta


Run
$ ssh localhost "echo \"Hello World\""
with bash does succeed. Hello World is shown in stdout.

Run distributed shell with similar echo command. That is
$ /usr/bin/yarn  org.apache.hadoop.yarn.applications.distributedshell.Client -jar /usr/lib/hadoop-yarn/hadoop-yarn-applications-distributedshell-2.*.jar
-shell_command "echo \"Hello World\""
