------------------------------------
Summary: 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
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.
