Aaron Fabbri commented on HADOOP-13449:
---------------------------------------
Thanks for feedback [~eddyxu]. Turns out a user can provide URIs for any number
of buckets. They will each have their own S3AFileSystem of course.
I actually ran into this running integration tests (this is the last failure I
have for my S3AFileSystem integration work). Some of the S3A Scale integration
tests hit s3a://landsat-pds in addition to the test filesystem. This caused a
failure when I had paths from both buckets in my MetadataStore, without the
leading scheme+host (bucket) to differentiate between the two.
I'm proposing that any FS client that supplies a Path without a host component
will get an exception, if it should have one (i.e. S3AFileSystem should,
RawLocalFilesystem should not). I'll call it out when I post my next patch on
HADOOP-13651.
