Subject [jira] [Updated] (HIVE-9621) HiveServer2 http mode - embedded jetty should use SynchronousQueue
Date Fri, 13 Feb 2015 01:58:13 GMT

]

Thejas M Nair updated HIVE-9621:
--------------------------------
    Description: Noticed an unreproducible bug (customer reported), where HiveServer2 in http
mode would accept the incoming tcp connection but would not allocate a new thread to process
the request. Switching from LinkedBlockingQueue to SynchronousQueue fixes the issue and also
simplifies the threading model.  (was: Noticed an unreproducible bug (customer reported),
where jetty has some issue with the currently used LinkedBlockingQueue. Using SynchronousQueue
fixes the issue and also simplifies the threading model.)
