Oozie cannot execute shell

[gw...@orange.com]

Hello !

I currently have a problem with Oozie.

I have an hadoop cluster (Horton Works distribution) on a CentOs operating system, with 2 master nodes with namenodes, 1 edge node with oozie server, hive server etc... and 4 data nodes.
The coordinator is able to launch the workflow without any problem, but as soon as a shell script needs to be launched, even a very small script like the one below, I have an error message and the job fails :

#################
#!/bin/bash
echo "hello world"
#################

Here is the error message :
2014-04-18 19:00:05,047  WARN ShellActionExecutor:542 - USER[applicative_user] GROUP[-] TOKEN[] APP[myWorkflow] JOB[0000015-140418185613138-oozie-oozi-W] ACTION[0000015-140418185613138-oozie-oozi-W@dispatchAction] Launcher ERROR, reason: Main class [org.apache.oozie.action.hadoop.ShellMain], main() threw exception, Cannot run program "myShell.sh" (in directory "/var/opt/data/flat/data012/hadoop/yarn/local/usercache/applicative_user/appcache/application_1397725822170_4730/container_1397725822170_4730_01_000001"): error=13, Permission denied

Here is the version of Oozie client that I have :
Oozie client build version: 4.0.0.2.0.6.0-102

And here is the version of the Oozie server :
4.0.0.2.0.6.0

Solution I already tried :

1.     Check the rights in each of my data nodes in /var/opt/data/flat/data*, everything is normal with 755 permissions

2.     Try to launch only a small script I wrote on the Linux filesystem and put by myself on the HDFS, and, as described above, I got the same error "Permission denied".

I'm currently running an HDP 2.0 secured by Kerberos.

I was wondering if someone had any advice to "where to look", "where to investigate".
I already check the logs in /var/log/oozie/ and except this error I cannot see anything else.

Where can I investigate ?

Best regards.
