Regarding Issue with Multi-Lang in Storm

[Sitakant Mishra <si...@gmail.com>]

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:

directory

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,
