Divij Vaidya commented on KAFKA-12489:
--------------------------------------
I have made some changes in [https://github.com/apache/kafka/pull/12197] which
should help us understand whether the test is failing since file is directory
or because it doesn't exist! Note that one of the problems is that we are not
asserting the return value of File.createNewfiles() API, which could
potentially be false. After this PR is merged in, we should see better
exception messages to highlight the problem when this test fails.
