PS2, Line 17:
Some additional info that may be worth mentioning:

Impala has its own set of filesystems that support storage ids (block 
locations). This set is maintained in FileSystemUtil.SCHEME_SUPPORT_STORAGE_IDS.

Hadoop filesystems might still return LocatedFileStatus objects even if they 
are not included in Impala's FileSystemUtil.SCHEME_SUPPORT_STORAGE_IDS. E.g. 
S3AFileSystem is not included in this set, even though it returns 
S3ALocatedFileStatus objects that contain a dummy block location.

Therefore it is not enough to check if we got an instance of LocatedFileStatus, 
we need to use Impala's set to decide if we should create an Impala 
FileDescriptor object with block locations or not.
