Subject RE: Yarn resource request
Date Thu, 21 Nov 2013 03:57:55 GMT
That’s a known limitation of the current implementation of schedulers in
YARN. The API allows different requests of different sizes within the same
priority but the implementations of the schedulers do not support this.
For different sizes, one can either use different priorities or use the
highest size amongst the sizes within a priority.

Subject: Yarn resource request

Currently, resource requests for the same priority and locality are
expected to all be the same size, how will Application Master do for
different size? use different requests?
