WordCountTopology Error
Hi.
I have been following a storm-starter guide, but still faced a problem with
WordCountTopology. However, my ExclamationTopology runs successfully.
When I run WordCountTopology, it gives me an error below
--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 know it has something to deal with multilang, but don't know what exactly
it is.
Btw, I'm using
- Ubuntu 14.04LTS,
- Storm-0.10.0.
- Using terminal to run storm-starter
Thank you.

It works using bin/storm as suggested by Matthias J. Sax

There is no storm.py in multilang/resource by default. Should I copy
storm.py into multilang/resource? I haven't changed anything nor added. I
just followed storm-starter guide.

There should be a storm.py in multilang/resource so that splitsentence.py can import it. Did you change folder structure or delete storm.py or something else?
