When Oozie server is starting , it is unable to find oozie-client-<version>.jar.

On my cluster I found it at /<HDP folder>/oozie-client-<version>.jar

That jar may have gotten deleted on your machine for some reason.

Please let me know if this helps. Thanks

Looks like we did some mistake while doing rpm cleanup. Copied oozie client jar to /usr/hdp/<version>/oozie/lib/ and it worked fine.

Thanks!
