You can verify this by running /bin/mount and checking the mount options. If you are able to, remount /tmp without noexec and try starting the NodeManager again. I am sure its issue with noexec on /tmp. </P> Wed, 16 Dec 2015 06:56:09 GMT pardeep_kumar 2015-12-16T06:56:09Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Unable-to-start-NodeManager-no-leveldbjni64-1-8-in-java/m-p/99487#M12664 <P>Cannot bring up 2 NodeMangers, the other 19 works fine.
