Sean Mackrory updated HADOOP-14499:
-----------------------------------
Attachment: HADOOP-14499-HADOOP-13345.002.patch
Attaching a patch that:
* Resolves the findbugs issue that started this
* Does not attempt to do any clean up of directories in Local
* Updates the javadoc on prune() in MetadataStore to be files only, not
directories (I don't think the interface as currently written makes it possible
to safely prune directories without hitting the same concerns as here).
* Keeps the same test from the .001. patch, unmodified
Re-tested with -Ds3guard -Dauth. ITestS3AContractRename and
ITestS3AInconsistency failed during the parallel test run because their fork-#
directories were missing, etc. Passed when re-run in isolation, but those
failures are new. Must be unrelated to this, though.
