-----------------------------
Summary: Make it possible to use the ShellBolt without having the
need to have resources
Key: STORM-90
URL: https://issues.apache.org/jira/browse/STORM-90
Project: Apache Storm (Incubating)
Issue Type: Improvement
Reporter: James Xu
Priority: Minor
https://github.com/nathanmarz/storm/issues/678
Hi,
there seems to be a problem in the ShellBolt that I would like to figure out.
If you use Storm multilanguage features and you try to communicate with a C++
using something like StormCpp it will possibly fail as long as you embed the
resource direclty (Also see nathanmarz/storm#229). But if you just have a
simple running executable that is placed in a PATH folder (like /usr/local/bin
on Linux) it will fail with "Caused by: java.io.IOException: Cannot run program
"xy"". The problem seems to be the ShellProcess - class where it does something
like setting the directory to the codeBaseDir which is set to the resource -
folder. As long as you have not assigned a resource - folder in your maven file
it will always fail. Something like:
<build>
<resources>
<resource>
<directory>${basedir}/SomeDirectory</directory>
</resource>
</resources>
</build>
will fix it but it's only a workaround. I can also provide you with a simple
code-example if needed. A possible solution would be that the ShellProcess
should check if the codeBaseDir exists so that I cannot fail.
