[jira] [Commented] (MESOS-1279) Add resize task primitive

["Kannan Rajah (JIRA)" <ji...@apache.org>]

Kannan Rajah commented on MESOS-1279:
-------------------------------------

This JIRA has not been updated in a year. This feature will benefit Apache Myriad which launches place holder tasks to represent the YARN containers. These container sizes will keep varying and so we need a way to resize the place holder tasks to avoid wasting resources. Currently, we are thinking of a workaround in Myriad itself. But I would like to know if there is a plan on when the feature will be implemented.

> As mentioned in MESOS-938, one way to support task replacement and scaling could be to split the responsibility into several smaller primitives for 1) reducing complexity 2) Make it easier to comprehend and 3) easier and incremental in implementation.
> resizeTask() would be the primitive to either
> 1) Scale a running task's resources down
> 2) Scale a running task's resources up by using extra auxiliary offers.
