Lefty Leverenz commented on HIVE-17426:
---------------------------------------
Config review: Please use newlines in the description of
*hive.print.task.graph* so that it won't all be on one line in the generated
template file (hive-default.xml.template).
While you're at it, you could edit the description of
*hive.repl.approx.max.load.tasks* which was added by HIVE-16896:
bq. Provide and approximate of the max number of tasks that should be executed
in before dynamically generating the next set of tasks. The number is an
approximate as we will stop at slightly higher number than above, the reason
being some events might lead to an task increment that would cross the above
limit
Suggested edits:
bq. Provide an approximation of the maximum number of tasks that should be
executed before dynamically generating the next set of tasks. The number is
approximate as Hive will stop at a slightly higher number, the reason being
some events might lead to a task increment that would cross the specified limit.
Trivia: Indentation should be standardized for both configs, same as for
adjacent configs.

> the execution framework currently only runs MR Tasks in parallel when {{set
> hive.exec.parallel=true}}.
> Allow other types of tasks to run in parallel as well to support replication
> scenarios in hive. TezTask / SparkTask will still not be allowed to run in
