I'm trying to launch Apache Twill application from hadoop cluster, the cluster is recently upgraded from HDP 2.2 to HDP 2.5 but I'm getting llegalAccessError for RequestHedgingRMFailoverProxyProvider class . This class is part of org.apache.hadoop.yarn.client package. I'm getting this error in the Application Master. The job status goes directy to 'not running state' right after 'accepted state'.

In general when you see IllegalAccessError this means you have a runtime incompatibility between compiled and runtime code. In this case,
the getProxyInternal() method of ConfiguredRMFailoverProxyProvider is now private. You need to recompile your client code and/or use updated hadoop client libraries to connect to your cluster.
