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.
