Sure Tom. I have added myself as reviewer. Read up on Noop described in thesis paper and self and Faiz had a detailed discussion today morning.
Overall the patch looks functionally complete. Will be going into detailed review.

We put a hack in Be to workaround it. This patch in master https://git.opendaylight.org/gerrit/#/c/42728/ explains the scenario and implements a proper solution. Muthu - feel free to review as I can't add you :) On Thu, Aug 4, 2016 at 12:29 PM, Muthukumaran K <muthukumara...@ericsson.com<mailto:muthukumara...@ericsson.com>> wrote: Hi, I want to understand under which condition, this exception seen in InMemoryDataTree.java#commit is thrown ? Does this exception mean that a child is being added by one Txn for a parent which could have been deleted another Txn ? I checked related bug in OVSDB – https://bugs.opendaylight.org/show_bug.cgi?id=5062 which shows similar stack trace but could not conclude the condition of this exception Regards Muthu _______________________________________________ controller-dev mailing list controller-dev@lists.opendaylight.org<mailto:controller-dev@lists.opendaylight.org> https://lists.opendaylight.org/mailman/listinfo/controller-dev
