Hi @steveloughran, thanks for the review. The transient failure in
HADOOP-17797 has been observed in each of these tests:
testWithAbfsIteratorDisabled, testWithAbfsIteratorDisabledWithoutHasNext,
testAbfsIteratorWithoutHasNext
The failure seems to be associated with the list of fileNames that is
populated by the executor task on creating test files. Was able to reproduce it
a few times, and found that failure always results from this list missing a
filename. Have added an assert to verify addition to list whenever a test file
is created. The failure seems to stem from concurrency-related issues within
the test as opposed to list iterator functionality, so the initial asserts
should help us distinguish these from actual listing errors
