Subject [jira] [Commented] (MAPREDUCE-4306) Problem running Distributed Shell applications as a user other than the one started the daemons
Date Thu, 07 Jun 2012 21:34:23 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4306?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291321#comment-13291321
] 

Ahmed Radwan commented on MAPREDUCE-4306:
-----------------------------------------

To reproduce this issue using the tarball on a single node cluster:

1- Start all the daemons using user1.
2- Switch to user2 and try to submit a distributed shell job:
{code}
bin/hadoop jar ./share/hadoop/mapreduce/hadoop-yarn-applications-distributedshell-3.0.0-SNAPSHOT.jar
org.apache.hadoop.yarn.applications.distributedshell.Client --jar ./share/hadoop/mapreduce/hadoop-yarn-applications-distributedshell-3.0.0-SNAPSHOT.jar
--shell_command ls --num_containers 1 --debug
{code}

I'll be uploading a patch momentarily.

> Using the tarball, if you start the yarn daemons using one user and then switch to a
different user. You can successfully run MR jobs, but DS jobs fail to run. Only able to run
DS jobs using the user who started the daemons.
