------------------------------------

             Summary: RBF: Print stacktrace when DFSRouter fails to fetch/parse JMX output
from NameNode
                 Key: HDFS-15100
                 URL: https://issues.apache.org/jira/browse/HDFS-15100
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: rbf
            Reporter: Akira Ajisaka
            Assignee: Akira Ajisaka


When DFSRouter fails to fetch or parse JMX output from NameNode, it prints only the error
message. Therefore we had to modify the source code to print the stacktrace of the exception
to find the root cause.
