Aaron T. Myers commented on HDFS-5289:
--------------------------------------
Thanks a lot for the review, Todd. I'm quite confident that the test failure is
unrelated. I'm going to commit this momentarily.
> Race condition in TestRetryCacheWithHA#testCreateSymlink causes spurious test

> The code to check if the operation has been completed on the active NN can
> potentially execute before the thread actually doing the operation has run.
> In this case the checking code will retry the check if the result of the
> check is null. However, the test operation does not in fact return null,
> instead throwing an exception if the file doesn't exist yet. We need to catch
> the exception and retry.
