[jira] [Created] (HIVE-3041) create a timeout for locks

Namit Jain created HIVE-3041:
--------------------------------

             Summary: create a timeout for locks
                 Key: HIVE-3041
                 URL: https://issues.apache.org/jira/browse/HIVE-3041
             Project: Hive
          Issue Type: Bug
            Reporter: Namit Jain


A common problem that we have seen in hive concurrency is as follows:

A table/partition is being read by a lot of clients.
This leads to starvation of the writer, since new readers are always coming
up. There should be a way to add a configurable timeout for the writer,
default can still be 0 to preserve the current behavior.

This should be very easy to do via the default concurrency manager, 
ZooKeeper, but should be do-able via other implementations (in the future)
also.
