MapR client giving UnsatisfiedLinkError

Hi,

We have configured a MapR cluster on AWS and have installed Mapr client on a different machine (based on Amazon Linux AMI).

The MapR client is able to connect to the MapR cluster and do a file listing ('hadoop fs -ls /'). However our webapplication which is deployed on tomcat and using HBase API is giving following error :

     java.lang.UnsatisfiedLinkError: com.mapr.security.JNISecurity.SetParsingDone()V

which suggests problem with the native MapR libraries. We have already configured java.library.path as VM arguments and could see that it's getting sent to the Tomcat container, still we are getting the error.

Please let us know how to proceed further on this. Note that same application is working fine against the local MR cluster, where the client is installed on Windows machine.

The full stack-trace is [attached][1].
