Hi All, Yesterday I tried migrating from 0.8.3-wip to the latest release 0.9.0.1 + Netty and it fails. The topology just hangs for no apparent reason ( nothing in the worker`s or supervisor`s logs. I guess something will eventually timeout but I let it ran for about 30 minutes and no batch have completed. Each batch usually takes about 1-2 minutes to process but not 30 minutes.
I tried the same topology under ZeroMQ works fine and I got slightly better performances over 0.8.3. The config I used for the transport is: storm.messaging.transport: "backtype.storm.messaging.netty.Context" storm.messaging.netty.server_worker_threads: 1 storm.messaging.netty.client_worker_threads: 1 storm.messaging.netty.buffer_size: 5242880 storm.messaging.netty.max_retries: 31 storm.messaging.netty.max_wait_ms: 10000 storm.messaging.netty.min_wait_ms: 1000 This is basically the config I found on the net. I`ve only changed the max_retries after I got some timeout during the startup phase. Any idea what could cause this? Am I the only one to run into this issue? We are still using Java 1.6 here... we had a bad experience with Java 7 and Storm a couple of months ago so I am not eager to move this project to Java 7 but will do it if helps. Thanks for your time and input.
