Mark Owens commented on ACCUMULO-4793:
--------------------------------------
It is a sub-task. 4793-4796 are sub-tasks of the overriding 4355 ticket. I
broke out the four individual requests into separate sub-task tickets. I copy
and pasted much of the text from 4355 into each ticket for background.
> Prioritize/Reprioritize bulk import requests

> Key: ACCUMULO-4793
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4793
> Project: Accumulo
> Issue Type: Sub-task
> Components: master, tserver
> Reporter: Mark Owens
> Priority: Major
>
> Accumulo currently provides mechanisms to initiate bulk imports and to list
> bulk imports in progress. Scheduling of bulk import requests is not entirely
> deterministic, and most of the execution of a bulk-import request is done in
> a non-preemptable manner. As such, any bulk import which takes very long to
> complete can block bulk imports with higher operational priority for
> significant periods.
> To better support bulk-import-heavy applications, it would be nice if
> Accumulo would offer additional mechanisms for controlling the scheduling and
> execution of bulk imports.
> One such capability would be the ability to prioritize and re-prioritize bulk
> import requests. Recent discussions with customers reveal this to be the
> highest priority on their feature request wish list.
