      Description

      Need to use 'new String(byte[])' instead of 'byte[].toString()' when converting to String for jdbc, in SQLOperation.convertLazyToJava()
      Need to add support for binary in jdbc driver code.

      THe exception that gets thrown while trying to access binary column is like this -

          [junit] org.apache.hive.service.cli.HiveSQLException: java.lang.ClassCastException: [B cannot be cast to java.lang.String
