URL: https://github.com/apache/accumulo/issues/5524
**Is your feature request related to a problem? Please describe.**
The property `manager.rename.threadpool.size` is used to control the number
of threads used for renaming files for bulk import. The implementation will
create a thread pool of this size per bulk import operation. If there are F
fate threads and this property is R, then can create up to F*R threads in the
worst case. Eventually too many threads will start to cause problems. Also
since the thread pools are per bulk import, can not easily track metrics on the
thread pools.
**Describe the solution you'd like**
A single thread pool in the manager that all bulk imports use would offer
two advantages.
* More predictable control over resources
* Ability to track metrics related to the rename pool
This single thread pool could hang off of server context.
**Additional context**
Changing the implementation behind this property could negatively impact
current systems w/ current settings for this property as they would all of a
sudden have less threads for this work in some cases. So not sure where this
change should land if its done.
