Hi Ashish, the class `RequestHedgingRMFailoverProxyProvider` was only introduced with Hadoop 2.9.0. My suspicion is thus that you start the client with some Hadoop 2.9.0 dependencies on the class path. Could you please check the logs of the client what's on its class path? Maybe you could also share the logs with us. Please also check whether HADOOP_CLASSPATH is set to something suspicious.
Thanks a lot!
