------------------------------
Summary: Allow ShellBolt to set env vars (particularly PATH)
Key: STORM-160
URL: https://issues.apache.org/jira/browse/STORM-160
Project: Apache Storm (Incubating)
Issue Type: New Feature
Reporter: James Xu
Priority: Minor
https://github.com/nathanmarz/storm/issues/32
While trying to implement a multilang based bolt, I discovered that binaries
outside of /usr/bin, /usr/sbin, and /sbin, are not found despite being
installed in say, /usr/local/bin.
Is there a way to specify a PATH variable so when storm creates the sub shell,
these binaries can be located by name? If not, can we get one added?
----------
nathanmarz: This is a good idea. For the meantime, does using the full path of
the binary (e.g., /usr/local/bin/python) work around this issue?
----------
dinedal: That works for processes that don't require any other environment
variables.
Also, in cases where developers have multiple versions of a program (say, RVM)
and the production servers have another one installed on the system, it means
changing code for deploying the topology.
----------
nicoo: +1
To work around this issue you can start your multilang bolt from a bash script
that set all needed env vars.
