I think I found what's happening. * CEP starts to synch from a Snapshot as soon as it got to know that there's a new member, hence, it complains that there're no exec. plans (other node is still starting up, hence no execution plans yet). (there was a NPE while doing this and I fixed it in https://github.com/wso2/siddhi/pull/135/files) * Then the active node, keeps trying till the other node gets to the correct state.
And I think we can implement an exponential backoff instead of doing the check one after another. Wdyt? On Tue, Apr 12, 2016 at 2:26 PM, Nirmal Fernando <[email protected]> wrote: > Yes me too.
