      Description

      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.
