Chris Douglas commented on HADOOP-14726:
----------------------------------------
FWIW, not making {{isDir}} final would not break compilation, but it would
cause infinite recursion in FileSystem implementations that override
{{isDirectory}} to call {{isDir}}, but {{isDir}} calls {{super.isDir}},
{{isDir}} is not overridden, etc.
Personally, I'd lean toward making {{isDir}} final to cause compilation
failures instead of this class of bugs for FileSystem implementations. But I'll
go with the prevailing taste consensus.
