Hi, I am trying to run the WordCountTopology in storm local mode before running my own application and I am unable to run it. I am continuously getting the following error. I have verified that the "splitsentence.py" file is kept at the "multilang/resources" directory.
5729 [Thread-22-split-executor[7 7]] ERROR o.a.s.util - Async loop died! java.lang.RuntimeException: org.apache.storm.multilang.NoOutputException: Pipe to subprocess seems to be broken! No output read. Serializer Exception: python: can't open file 'splitsentence.py': [Errno 2] No such file or directory at org.apache.storm.utils.ShellProcess.launch(ShellProcess.java:91) ~[storm-core-1.0.3.jar:1.0.3] at org.apache.storm.task.ShellBolt.prepare(ShellBolt.java:131) ~[storm-core-1.0.3.jar:1.0.3] at org.apache.storm.daemon.executor$fn__4973$fn__4986.invoke(executor.clj:791) ~[storm-core-1.0.3.jar:1.0.3] at org.apache.storm.util$async_loop$fn__557.invoke(util.clj:482) [storm-core-1.0.3.jar:1.0.3] at clojure.lang.AFn.run(AFn.java:22) [clojure-1.7.0.jar:?] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_51] 5734 [Thread-30-spout-executor[9 9]] INFO o.a.s.d.executor - Opening spout spout:(9) 5734 [Thread-28-split-executor[6 6]] ERROR o.a.s.util - Async loop died! I have followed the instructions during installation and built my package successfully with maven. My storm version is 1.0.3 and my python version is 2.7.13. I am not able to understand why the multi-lang support in storm is not working. Any help with this is greatly appreciated. Thanks and Regards, Sitakanta Mishra
