Hive param substitution on Azkaban issue #145

An example of using hive param

Job file:
hiveconf.zipcode=95132

Hive script file:
select member_id, postal_code from member_table where and postal_code = '${hiveconf:zipcode}';

Hive also supports a "-hivevar x=y" command line switch that allows you to define substitution variables without polluting the HiveConf. Is this already supported, or do we need to add support for it in this patch?
