Subject [jira] [Created] (HIVE-5244) Concurrent query compilation in HiveServer2
Date Mon, 09 Sep 2013 07:20:51 GMT
Vaibhav Gumashta created HIVE-5244:

             Summary: Concurrent query compilation in HiveServer2
                 Key: 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.
