> system tests: error copying keytab file

> Key: KAFKA-2851
> URL: https://issues.apache.org/jira/browse/KAFKA-2851
> Project: Kafka
> Issue Type: Bug
> Reporter: Geoff Anderson
> Assignee: Anna Povzner
> Priority: Minor

> It is best to use unique paths for temporary files on the test driver machine
> so that multiple test jobs don't conflict.
> If the test driver machine is running multiple ducktape jobs concurrently, as
> is the case with Confluent nightly test runs, conflicts can occur if the same
> canonical path is always used.
> In this case, security_config.py copies a file to /tmp/keytab on the test
> driver machine, while other jobs may remove this from the driver machine.
> Then you can get errors like this:
