Review comment:
allPartDirs here contains all partition path which are there in
FileSystem but not in metastore. Removing it from partPathsInMS doesn't make
sense.
I think this operation should be done before
allPartDirs.removeAll(partPaths);

Review comment:
As you pointed out, Having multi-threaded check of partition files will
be useful.
