I am getting a Launcher Error while executing shell action in oozie workflow.

[#1]

Hi all,

I have created a shell action in oozie workflow. It was executing perfectly a while ago. Later day it started showing below error.

Launcher ERROR, reason: Main class [org.apache.oozie.action.hadoop.ShellMain], main() threw exception, Cannot run program "checkForFileExistance.sh" (in directory "/data1/hadoop/yarn/local/usercache/hadoop/appcache/application_1471524954637_0316/container_e27_1471524954637_0316_01_000002"): error=2, No such file or directory

Please help me with the error.

Please not that the shell script is available in lib folder under workflow directory.

@Vijay Kumar J - Do you have execute permissions on your shell script? Have you mentioned shell script correctly(with file and script tags) in your oozie workflow.xml?

Please refer this tutorial for more details:

It was an permission issue.

well I too have exactly same error. I have checked permissions on my script and it has execute permissions. @Vijay Kumar J is it possible for you to elaborate how it was resolved ?
