Hitesh Shah commented on YARN-193:
----------------------------------
@Zhijie, distributedshell is an example application and therefore explains how
to write a "good" application which checks what the limits are and changes its
requests accordingly.
IMO, for applications which do not respect the limits, instead of reducing
their defined requirements to the max value, we should throw an error as we are
not sure if the app really needs that high amount of resources and whether it
will actually if we reduce that amount to the max value.
Does that make sense?
