Is there any other cause of silent replays? We’re seeing batch replays even though tuple timeouts are turned off completely, and max_spout_pending is 1...

I can't seem to find anything or figure that out. Thanks On Wed, May 28, 2014 at 2:58 PM, P.

Try upping that value and setting TOPOLOGY_SPOUT_MAX_PENDING to a very low value like 1. In trident that controls how many batches can be in-flight at a time. -Taylor > On May 28, 2014, at 5:24 PM, Raphael Hsieh > <[email protected]<mailto:[email protected]>> wrote: > > Is there a way to add logging to the master coordinator? > For some reason my spout is failing batches and not giving me any error > messages. > The log files on the host don't provide any error messages and I'm not sure > where the logic for this resides in Storm-Trident. > > Is there a particular string other than 'failed' that I can grep for? > > Thanks > -- > Raphael Hsieh > > -- Raphael Hsieh
