hadoop - Submitting oozie jobs using keytab -

-

I am using a kitab file to bypass Kerberos to run a shell script via oozie The script also contains the hbase shell command I hbase nee to a kinit before running the shell command. It works fine for me.

So, in a case where I have to start a job using a coordinator and use a charity (service account) in many shell scripts workflow, would there be a collision in Ozzy? Since I launch a job using the Ozzy Coordinator, but keep the KTab files in the service account workflow.

Thanks,

Keytab files need to be present on all the headop data nodes is. They need your shell scripts while running an OOzi job / map task to execute kinit for service accounts.

While deploying the keytab files in the data nodes of the shared cluster, it is best to set the file permission correctly so that it will not be used near other HOP jobs.

Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
