Remove logging exception stack trace when one of the datanode targets to read from is not reachable
---------------------------------------------------------------------------------------------------

                 Key: HDFS-1906
                 URL: https://issues.apache.org/jira/browse/HDFS-1906
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs client
    Affects Versions: 0.20.203.1
            Reporter: Suresh Srinivas
            Assignee: Suresh Srinivas
            Priority: Minor
             Fix For: 0.23.0
         Attachments: HDFS-1906.patch

When client fails to connect to one of the datanodes from the list of block locations returned,
exception stack trace is printed in the client log. This is an expected failure scenario that
is handled at the client, by going to the next location. Printing entire stack trace is unnecessary
and just printing the exception message should be sufficient.
