Subject Why resource requests are normalized in RM ?
Date Thu, 12 Jun 2014 00:52:59 GMT
Hi,
Anyone knows why resource requests from AMs are normalized to
be multiples of yarn.scheduler.minimum-allocation-mb which is 1G
by default ?
Also is there any problem with reducing yarn.scheduler.minimum-allocation-mb
to less
than 1G ?

 /**

   * Utility method to normalize a list of resource requests, by insuring
that

   * the memory for each request is a multiple of minMemory and is not zero.

   */

SchedulerUtils.normalizeRequests()

Thanks,
Ashwin
