-------------------------------
Summary: Move QueryLifeTimeHook out of compilation lock
Key: HIVE-14664
URL: https://issues.apache.org/jira/browse/HIVE-14664
Project: Hive
Issue Type: Bug
Reporter: Chao Sun
Assignee: Chao Sun
QueryLifeTimeHook currently triggers inside {{Driver#compile}} method, which is
protected by the global compile lock. This poses a potential issue: since one
can do anything inside a Hook, even running a Hive query, it may incur
potential deadlock. To resolve this, we should consider move it out of the
method and perhaps put in {{Driver#compileInternal}}
