Hi all, Recently I'm looking at HAMA-387.
There's some problem related with lock and barrier synchronization. The problem is as soon as last one of lock files deleted (before completely escape from while loop at leaveBarrier method), others begin to create their lock file. So, sometimes, it causes hang. My temporary solution is 'Thread.sleep(200);'. Good but not perfect. If zk.getChildren() response is slower than 200 milliseconds, process will be hanged. Is there any other idea? Thanks. -- Best Regards, Edward J. Yoon @eddieyoon
