Lei (Eddy) Xu commented on HDFS-10637:
--------------------------------------
bq. Can you confirm which one are you referring to?
Sure. I mean you can remove {{FsVolumeImpl#currentDir}} as a class member, as
it can be derived from {{FsVolumeImpl#storageLocation}}.
bq. FsDatasetSpi#getFileInFinalizedDir().
It still assumes {{FsDatasetSpi}} is backed by {{java.io.File}}. If this is
only used by tests, can you use {{FsDatasetTestUtils#getBlockFile}} and
{{#getMetaFile}}, as they are in the test package. So that {{FsDatasetSpi}} is
clean from {{java.io.File}}?
Thanks.
