Eric Newton created ACCUMULO-4042:
-------------------------------------
Summary: slow shutdown
Key: ACCUMULO-4042
URL: https://issues.apache.org/jira/browse/ACCUMULO-4042
Project: Accumulo
Issue Type: Bug
Components: master
Affects Versions: 1.6.4
Environment: Very large production cluster.
Reporter: Eric Newton
Fix For: 1.8.0
Clean shutdown is taking minutes. May need to use a threadpool approach to for
the final lock removal. All tablets were already unloaded, but the final steps
(tserver lock removal, for example) took a long time with so many servers.
