Vinod Kumar Vavilapalli updated HADOOP-2961:
--------------------------------------------

    Attachment: HADOOP-2961

Attaching patch. This also addresses HADOOP-2946 and HADOOP-2949.

 - When external host is not specified or set to False in either gridservice-mapred or hdfs sections and if any of tracker_port/info_port/fs_port is *missing*, HOD no longer complains. Earlier, it used to fail saying "tracker_port/info_port/fs_port are not defined", even though they are not used at all.
 - When external host is not specified or set to False in either gridservice-mapred or hdfs sections and any of tracker_port/info_port/fs_port or _host_ is *invalid*, HOD no longer complains. Earlier, it used to fail saying invalid tracker_port/info_port/fs_port or _host_ is specified , even though they are not used at all.

HADOOP-2946:
 - Currently HOD client side *does not* check for the pkgs directory in gridservice-hdfs. But it *is* needed to be checked on the ringmaster where it *is* going to be used, irrespective of whether the external option is specified or not.. So, no fix needed for HADOOP-2946, leaving it as invalid.

HADOOP-2949:
 - If tarball is specified, HOD no longer validates for the pkgs directory in gridservice-hdfs or mapred sections as these are not going to be used anyway. Earlier, it used to validate and fail with error code 6 (Ringmaster failure).

> When external host is not specified in gridservice-mapred or hdfs sections, there is no point in HOD validating the port numbers or hostnames.
