Hi All, I simplified my algorithm and the issue has disappeared.

I submit the job via the hama command interface, and it seems to execute perfectly. Tailing of the groom server logs shows succesfull completion. The forked GroomServer.Child processes shutdown, but the job never fully completes. On the BSPMaster, running jstack on the hama.util.RunJar process shows the main thread still blocked on BSPJob.waitForCompletion(true). I've looked through the logs of master, zookeeper, and grooms and everything looks good afaik. Here is the source of my program: https://github.com/willmore/hama-kmeans/blob/master/src/main/java/ee/ut/cs/willmore/KMeansCluster.java Any pointers would be greatly appreciated. Cheers, Chris
