Gour Saha commented on AMBARI-10644:
------------------------------------
Thanks to [~srimanth.gunturi] for helping debug this. We figured that the
commons-io jar in the slider view is v2.1. This version does not have class
{{org.apache.commons.io.Charsets}}, which class
{{org.apache.hadoop.ipc.ProtobufRpcEngine}} in hadoop 2.7.1 now depends on.
We replaced the v2.1 commons-io jar in the slider view with v2.4 and restarted
ambari-server. Now Slider view page opens without any errors.
Will provide a patch with the modified Slider view pom.
This is the exception stack which is the root cause of this issue -
