Koji Noguchi commented on HADOOP-7262:
--------------------------------------
bq. Capacity Guarantees
bq.
Isn't 'guarantee' a strong word to use for the current capacity scheduler?
This is only possible when all of the queues have max-limit equal to queue
capacity (since we don't have preemption).
bq. If true, priorities of jobs will be taken into account in scheduling
decisions.
bq.
On our internal cluster, we've never tried this. It was once pointed out that
we still have priority inversion problems(MAPREDUCE:314) and should not enable
this conf. Was this fixed ? If not, should we mention that it is not being
used/tested yet?
