Yufei Gu updated YARN-5774:
---------------------------
Description:
The problem is in the code used by both Capacity Scheduler and Fair Scheduler.
scheduler.increment-allocation-mb is a concept in FS, but not CS. So the common
code in class RMAppManager passes the yarn.scheduler.minimum-allocation-mb as
incremental one because there is no incremental one for CS when it tried to
normalize the resource requests.
{code}
SchedulerUtils.normalizeRequest(amReq, scheduler.getResourceCalculator(),
scheduler.getClusterResource(),
scheduler.getMinimumResourceCapability(),
scheduler.getMaximumResourceCapability(),
scheduler.getMinimumResourceCapability()); --> incrementResource
should be passed here.
{code}
was:
{code}
SchedulerUtils.normalizeRequest(amReq, scheduler.getResourceCalculator(),
scheduler.getClusterResource(),
scheduler.getMinimumResourceCapability(),
scheduler.getMaximumResourceCapability(),
scheduler.getMinimumResourceCapability()); --> incrementResource
should be passed here.
{code}
> A wrong parameter is passed when normalizing resource requests
