J.Andreina created HDFS-3406:
--------------------------------

             Summary: Secondary Namenode does not do checkpointing and Exception message is
thrown for ever when "dfs.namenode.checkpoint.dir" and "dfs.namenode.checkpoint.edits.dir"
are configured to an invalid value
                 Key: HDFS-3406
                 URL: https://issues.apache.org/jira/browse/HDFS-3406
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: J.Andreina
            Priority: Minor
             Fix For: 2.0.0, 3.0.0


When "dfs.namenode.checkpoint.dir" and "dfs.namenode.checkpoint.edits.dir" are configured
to an invalid value.
Started NN,DN and SNN

At the SNN side checkpoint does not happens and exception is thrown continously 
Expected:
==========
When all the configured values are invalid then Secondary Namenode need not continue and keeps
throwing exception for every checkpointing period 
Instead the SNN should get shutdown throwing an exception as Illegal Argument passed.

SNN side logs:
