Parth Brahmbhatt commented on KAFKA-2587:
-----------------------------------------
[~ijuma] I tried to reproduce this locally by running the test in loop for 50
times and it never failed.
{code}
for i in `seq 1 50`; do ./gradlew clean core:test
-Dtest.single=SimpleAclAuthorizerTest; done
{code}
Just analyzing the failure shows that the transient failure is reported during
removal of the acl on this line.

Looking at the code given we update the local authorizer's cache immediately I
am not entirely sure why would we see transient failures. I have modified the
failure message to indicate a little bit more debug info and I have bumped up
the timeout from 5 seconds to 10 seconds in case notification processing delay
interleaved with the changes made to cache is somehow resulting in this failure.
