--------------------------------------
Summary: Concurrent query compilation in HiveServer2
Key: HIVE-5244
URL: https://issues.apache.org/jira/browse/HIVE-5244
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Reporter: Vaibhav Gumashta
Assignee: Vaibhav Gumashta
Currently, in an HS2 process, multiple threads block on query compilation
(check Driver#runInternal) due to coarse level threading at the Driver class
object level. This can be a severe performance bottleneck, especially for a
remote server serving multiple clients.
