---------------------------------
Summary: The keepalive logic is incomplete in ProcedureExecutor
Key: HBASE-19978
URL: https://issues.apache.org/jira/browse/HBASE-19978
Project: HBase
Issue Type: Bug
Reporter: Duo Zhang
The worker thread will just exit after keep alive time, and we never add it
back. The only way to add it back is through the stuck checker, this is not
correct. Here we should start new worker thread if it is under the core pool
size and there are pending procedures.
For now the default keep alive time is Long.MAX_VALUE which means no timeout so
no problem, but we do allow users to set it so we need to fix it.
