Amithsha commented on MAPREDUCE-7123:
-------------------------------------
This we found in nodemanager where 2.9.0 hadoop is installed and the framework
path is pointed to 2.7.1.
This lead to job failures on the cluster randomly.
Ex:
During restart of this particular node will cause the AM to fail with following
exception.
