Dear Storm User Group!
We are experimenting with Storm 0.9.0.1 and having an issue with deploying the Storm-Starter demo cluster to our test environment (which consists of a master server and - for now - a single server running one supervisor): We experience the following java exception from (in the supervisor log): 2014-01-17 10:25:13 b.s.d.worker [ERROR] Error on initialization of server mk-worker java.io.FileNotFoundException: File '/home/elsztok/storm_tmp/supervisor/stormdist/mytopology-6-1389892683/stormconf.ser' does not exist We have already tried the following: 1. Restart the topology (kill and restart) 2. Restart Nimbus and the supervisor, redeploy topology 3. Restart Zookeeper, restart Nimbus, restart supervisor, redeploy topology We have used the info available on https://github.com/nathanmarz/storm/wiki/Setting-up-a-Storm-cluster to setup our simple cluster. Everything was working on LocalTopology correctly, it seems the problem is with the deployment and-or Storm configuration. There are no other errors apart from this one. Also, the UI does not show streams processing and bolt operation. The stormconf.ser and its directory is accessible by the "user" user. We are compiling and running with the same Storm library version. In some threads we have seen questions and answers about issues similar to this, however they relate to a different (mostly earlier) storm version, and states that the error was fixed on 0.9.0-rc3 Considering this, we would like to ask the following: 1. Can it be that we are using a wrong ZooKeeper version (3.4.5 instead of 3.3.3)? (Right now we cannot switch the version because the system is under use by others.) 2. Do you have any other suggestions apart that we have already tried out to solve this problem? Thank you very much in advance! Attila Tóth
