Chris Nauroth updated FALCON-889:
---------------------------------
    Attachment: FALCON-889.1.patch

[~svenkat], thank you for pointing out this issue to me.  I'm attaching the proposed patch.

The problem is that Falcon tried to pass a {{Path}} (a URI) with "wasb" as the scheme to an HDFS file system (class {{DistributedFileSystem}}) instead of a WASB file system (class {{NativeAzureFileSystem}}).  We have validation checks in place to block this, because it could be disastrous to operate on a path in an unintended file system by mistake.

Inside {{FileSystemStorage}}, the {{FileSystem}} instance was always created based on {{fs.defaultFS}}.  Therefore, this code path was only working if the destination is the default file system.  The patch changes the call to get the {{FileSystem}} so that it's sensitive to the specific {{Path}} (and therefore its scheme).
