[jira] [Commented] (MESOS-3078) Recovered resources are not re-allocated until the next allocation delay.

["Guangya Liu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-3078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14727554#comment-14727554 ] 

Guangya Liu commented on MESOS-3078:
------------------------------------

The MESOS-3157 is a similar issue, the solution is removing all the event-triggered allocations to reduce event queue and only allocate from the batch task HierarchicalAllocatorProcess::batch. This works great and really improves responsiveness with lots of short-live frameworks

> Currently, when resources are recovered, we do not perform an allocation for that slave. Rather, we wait until the next allocation interval.
> For small task, high throughput frameworks, this can have a significant impact on overall throughput, see the following thread:

> We should consider immediately performing a re-allocation for the slave upon resource recovery.
