Marc Bush commented on KAFKA-4566:
----------------------------------
on REL, at least, I found the issue to be with the calling of a path with
$base_dir/../etc/etc/etc
it's the .. that kept on causing the OS to evaluate the path as the "real" path
instead of the symlink version of the path.
I'm my case I use one source location of the kafka files then tor run a number
of zookeepers and brokers I have directories that inside symlink back to the
/bin and /lib directories of the source allowing me to have unique config
directories in each other instance.
Until I recoded the /../ parts upon startup everythign would redirect and try
to use everything from the source binaries and configs, after I modified them I
was able to properly use the source binaries and my own unique config location.
I'll pull my changes from my code and post them tomorrow when I have a spare
moment.
This "fix" only involved updating 3 files
> Can't Symlink to Kafka bins

> Key: KAFKA-4566
> URL: https://issues.apache.org/jira/browse/KAFKA-4566
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Affects Versions: 0.10.1.1
> Reporter: Stephane Maarek
> Assignee: Akhilesh Naidu
> Labels: newbie
>
> in the kafka consumer for example, the last line is :
> https://github.com/apache/kafka/blob/trunk/bin/kafka-console-consumer.sh#L21
> {code}
> exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleConsumer "$@"
> {code}
> if I create a symlink using
> {code}
> ln -s
> {code}
> it doesn't resolve the right directory name because of $(dirname $0)
> I believe the right way is to do:
> {code}
> "$(dirname "$(readlink -e "$0")")"
> {code}
>
> Any thoughts on that before I do a PR?
