Hi, I was having the same problem as described in this and other threads: https://groups.google.com/forum/#!topic/storm-user/iwsDPT8O3gw
Namely seeing this error message in log files: worker [ERROR] Error on initialization of server mk-worker java.io.IOException: No such file or directory It turned out that my logback/cluster.xml configuration had a SocketAppender that didn't have a listener on the remote host. Having an appender defined in configuration file, even if it is not set up to receive any log messages, will cause Storm to block and the above error message. Hope this helps someone.
