Webhcat resource /templeton/v1/status doesn't track Hive job progress

Problem: Unable to track Hive job progress through webhcat.
Cause:
TempletonUtils has code to parse PIG and JAR child jobid and percentage progress but none for Hive jobs. extractPercentComplete() and extractChildJobId() are supposed to do this parsing.
Effect:

/templeton/v1/queue/$job_id?user.name=$user returns no job progress info. The jobid param in the json result that's supposed to contain the child hive jobid contains the templetoncontrollerjob id instead leaving the parent jobid null.
