Steve Loughran commented on HADOOP-13139:
-----------------------------------------
-1 to patch 003
the problem I'm seeing is that as soon
{code}
mvn test -Dtest=TestS3A\* -Pparallel-tests -DtestsThreadCount=2
...
{code}
I don't what's happening, but if it's happening here, it's presumably happening
in trunk too...just nobody is doing parallel tests there.
While it's easy to dismiss this as one of the "not so good to run in parallel"
tests, we need to understand more why this is. I suspect it may just be that
the parallel test is initing the same object store during the test, as as
multipart purge is set to true + 0; that's enough to break things.
Notable that we're getting 404 as a failure here, which is being remapped to an
FNFE in our code. Is that the right reaction?
