Raghotham Murthy updated HIVE-713:
----------------------------------
Attachment: hive-713.1.donot.patch
This patch contains most of the changes to the APIs in the ql package. It is
only for review. The following need to be done:
* Add the following default counters to Operator: #input rows, # output rows,
cputime
* In QueryPlan, fetch the counters from the active tasks and store them locally
to be queried later
* Add progress method to MoveTask(?) and CopyTask
* Dump stats to history file in all progress methods
* Dump the query plan so that it can be viewed using tools like graphviz
* Change CliDriver or create a new class which can reconstruct the plan
annotated with counters from logs in history file
* Provide a call in HiveServer to retrieve the annotated query plan
> Integrate operator counters into query plan to view progress of queries
