Description
It seems the lock contention due to the file limit in FileManager is still an issue in 1.9. This problem has been around since https://issues.apache.org/jira/browse/ACCUMULO-416 which is a prerequisite for https://issues.apache.org/jira/browse/ACCUMULO-543. It would be worthwhile to revisit the first ticket and at the very least have a config option to disable the file limit lock.
Contributor guide
Research direction
Start by reviewing ACCUMULO-416 and the current FileManager implementation to understand how the scan file limit lock causes contention. Trace the existing configuration and locking behavior, then verify that a configuration option can disable the limit lock without disrupting scans and add coverage for the resulting behavior.
