Major Description
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
The ability to pause in-progress bulk imports and then rresume them is desired.
