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 which is in the " *examples/storm-starter"* 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 ran the *ExclamationTopology* and some of my own code which does not need multi-language support and it works like a charm. I tried putting file in different locations and changing the relative path, but still it is not working. 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
