Steve Loughran updated HADOOP-14935:
------------------------------------
Attachment: HADOOP-14935-005.patch
I'm going to attach patch 005. This is patch 004 with all support for auth on
getFileStatus removed. That is, the code in patch 4 and HADOOP-14845 cut out:
there's no auth checking going on in that call.
I've not reverted all of HADOOP-14845; it retains the
{{getFileStatusInternal()}} and {{existsInternal()}} calls. Why so?
# In S3A it turned out to be useful to have the split, especially related to
error translation & retry
# makes it easier to reinstate file status auth; changes to production code
will be limited to getFileStatus only.
Testing Azure ireland.

> FileSystem implementation class for azure i.e. {{NativeAzureFileSystem}} does
> not override {{access(path,mode)}} method and uses the default implementation
> from the base class. This base implementaion uses the POSIX permissions to
> check if the requested user has access to given path or not even when
> authorization is enabled, which is incorrect.
> {{NativeAzureFileSystem.access()}} in authorization enabled mode should use
> the authorization mechanism provided instead of relying on the POSIX
> permission ons. So the proposal is to override {{FileSystem.access()}} method
> in {{NativeAzureFileSystem}} such that it honors the authorization mechanism
> configured in authorization enabled mode and falls back to POSIX permissions
> otherwise.
