Steve Loughran commented on HADOOP-12977:
-----------------------------------------
Patch applied to trunk and branch-2; the trunk patch was simply done by
skipping the s3 test; git lets you do this with ease
{code}
git apply -3 --verbose --whitespace=fix --exclude
hadoop-tools/hadoop-aws/src/test/java/org/apache/hadoop/fs/contract/s3/ITestS3ContractRootDir.java
HADOOP-12977-branch-2-006.patch
{code}
Branch-2.8 is another matter; I will do that quickly and attach under here again
> s3a to handle delete("/", true) robustly

> if you try to delete the root directory on s3a, you get politely but firmly
> told you can't
> {code}
> 2016-03-30 12:01:44,924 INFO s3a.S3AFileSystem
> (S3AFileSystem.java:delete(638)) - s3a cannot delete the root directory
> {code}
> The semantics of {{rm -rf "/"}} are defined, they are "delete everything
> underneath, while preserving the root dir itself".
> # s3a needs to support this.
> # this skipped through the FS contract tests in
> {{AbstractContractRootDirectoryTest}}; the option of whether deleting / works
> or not should be made configurable.
