-------------------------------
Summary: Add a shutdown hook manager in order to set priorities
Key: TAJO-1831
URL: https://issues.apache.org/jira/browse/TAJO-1831
Project: Tajo
Issue Type: Improvement
Components: Java Client, RPC, TajoMaster, Worker
Reporter: Jinho Kim
Assignee: Jinho Kim
Priority: Minor
Sometimes, event-group thread of netty’s is not stopped. because jvm will start
a shutdown-hook after all thread is stopped without kill signal. it is
dead-lock state.
We should explicitly call to shutdown the event-group thread of netty’s and
should set a shutdown-hook order
For example, before you start up TajoMaster, runs tsql, you can find deadlock
