Hi, I work with Storm for a while already, but want to get started with development. As suggested, I am using Intellij (up to now, I was using Eclipse).
I was also looking at https://github.com/apache/storm/tree/master/examples/storm-starter#intellij-idea This documentation is not complete. I was not able to run anything in Intellij first. I could figure out, that I need to remove the scope of storm-core dependency (in storm-starter pom.xml). (found here: https://stackoverflow.com/questions/30724424/storm-starter-with-intellij-idea-maven-project-could-not-find-class) After that I wass able to build the project. I can also run ExclamationTopology with no problems within Intellij. However, WordCountTopology fails. First I got the following error: > java.lang.RuntimeException: backtype.storm.multilang.NoOutputException: Pipe > to subprocess seems to be broken! No output read. > Serializer Exception: > Traceback (most recent call last): > File "splitsentence.py", line 16, in <module> > import storm > ImportError: No module named storm I was able to resolve it via: apt-get install python-storm (from StackOverflow) However, I don't speak Python and was wondering what the problem is and why I could resolve it like this. Just want to get deeper into it. Maybe someone can explain. Unfortunately, I am getting a different error now: > java.lang.RuntimeException: backtype.storm.multilang.NoOutputException: Pipe > to subprocess seems to be broken! No output read. > Serializer Exception: > Traceback (most recent call last): > File "splitsentence.py", line 16, in <module> > import storm > ImportError: No module named storm I did not find any solution on the Internet. And as I am not familiar with Python and never used Storm differently as low-level Java API I am stuck now. Because ExclamationTopology runs, I guess my basic setup is correct. What do I do wrong? -Matthias
