> Long classpath support
> ----------------------
>
> Key: SAMZA-1817
> URL: https://issues.apache.org/jira/browse/SAMZA-1817
> Project: Samza
> Issue Type: Bug
> Reporter: Sanil Jain
> Assignee: Sanil Jain
> Priority: Major
>
> Samza team could also support a problem for long classpath by implementing
> something that would reduce the classpath length.
> Some potential ideas to fix:
> - Change the generated classpath (done in Samza's bash scripts) to be a list
> of `<directory>/*jar` entries instead of a list of every individual jar.
> Wildcards in the classpath are supported in jdk >= 6.
> This should be a relatively simple change and can be implemented by getting
> the parent directory of all jar files into a list, sorting and making the
> list unique, then append a wildcard to the end to pick up all jars under each
> directory in the list (ask Jon Bringhurst if you have any questions).
> See
> https://github.com/apache/samza/blob/92ae4c628abb3d113520ec47ca82f08c480123ad/samza-shell/src/main/bash/run-class.sh#L63
> for where the code change for this should probably be.
> - Use the manifest in a special "uber-jar" to list all dependencies in the
> classpath. Then just include that one "uber-jar" in the classpath on the cli.
> This would probably be tough to do, and seems like it would be annoying to
> manage, but apparently IntelliJ uses this strategy.
> Note that this is not an issue with the number of arguments (argc limit,
> which is based on a multiple of the ulimit -s stack size), it is a problem
> with the length of a single argument (strlen(*argv) limit based on
> MAX_ARG_STRLEN, which is a multiple of the PAGE_SIZE). So, the only way to
> get around this limit is to recompile the kernel with a different page size
> (which obviously isn't practical).
