SOLR-5628: work arround for this test to avoid whatever bug is in the cloud
test framework (merge r1574941)
> Cloud test harness can cause index files to be deleted before IndexWriter is
> closed

> Key: SOLR-5628
> URL: https://issues.apache.org/jira/browse/SOLR-5628
> Project: Solr
> Issue Type: Bug
> Reporter: Hoss Man
>
> This bug was orriginally opened because Jenkins uncovered a test seed that
> causes a reproducible IndexWriter assertion failure in
> TestDistribDocBasedVersion on the 4x branch.
> McCandless helped dig in and believe that something in the way the solr test
> framework is setup is causing the test to delete the index dirs before the
> IndexWriter is being closed. Meanwhile, the failures later reproduced in
> other seeds on both 4x and trunk -- and it appears that recent changes caused
> the nature of the failure to change, so that now -- in addition to the
> IndexWriter assertion failure -- the test cleanup also stalls out and the
> test runner has to terminate some stalled threads.
> One interesting factor about this test is that at the end of the test there
> were docs that had been added that were not committed -- which is probably
> unusually for most tests, and may explain why more cloud tests aren't
> exhibiting similar symptoms more often.
> *When a useless (from perspective of what the test is trying to verify)
> "commit" was added to the test, the failing seed stoped reproducing.*
> An example of how to reliably reproduce this problem on an (older version of)
> trunk...
