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

    [ https://issues.apache.org/jira/browse/MESOS-3078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15432190#comment-15432190 ] 

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

The review posted by [~jjanco] here https://reviews.apache.org/r/51027/ can help this, we can use similar logic in {{addSlave}} to handle this.

{code}
allocationCandidates.insert(slaveId);
if (!allocationPending) {
  allocationPending = true;
  dispatch(self(), &Self::allocate);
}
{code}

> 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.
