> release tarball is unnecessarily large due to duplicate libraries
> -----------------------------------------------------------------

> Key: KAFKA-3250
> URL: https://issues.apache.org/jira/browse/KAFKA-3250
> Project: Kafka
> Issue Type: Bug
> Reporter: Gwen Shapira
>
> Between 0.8.2.2 and 0.9.0, our release tarballs grew from 17M to 34M. We
> thought it is just due to new libraries and dependencies. But:
> 1. If you untar Kafka into a directory and check the directory size (du -sh),
> it is around 28M, smaller than the tarball. Recompressing give you 25M
> tarball.
> 2. If you list the original tar contents and grep for "snappy", you see it 4
> times in the tarball.
> Clearly we are creating a tarball with duplicates (and we didn't before).
> I think its due to how we are generating the tarball from core but pull in
> other projects into libs/ directory with their dependencies (which overlap).
> We need to find out how to sort it out (possibly with excludes).
