Chris Nauroth updated HADOOP-11984:
-----------------------------------
Attachment: HADOOP-11984.011.patch
Even when {{TestCredentials}} runs in isolation, the parent directory isn't
there, so that rules out another concurrent test interfering. This is very
strange. Is something going wrong with the mkdir of the test directories
inside pom.xml? I wouldn't expect so, because we'd see error output and an
earlier failure in the build.
The fix might be just to change {{TestCredentials}} to use a recursive
{{mkdirs}}, which is what other tests do. I'm really curious about this
though, so patch v011 is one more troubleshooting patch that echoes the
directories that pom.xml tries to create. Let's see if these are any different
from what I see on my local machine.
> Enable parallel JUnit tests in pre-commit.
