Colin Patrick McCabe commented on HADOOP-10334:
-----------------------------------------------
I don't think this should be a hadoop-common thing. I think it should be an
hdfs-specific thing, with an hdfs-specific configuration key.
Different filesystems have different ways of setting their home directory. For
example, {{FTPFileSystem}} actually uses the home directory that the FTP server
uses (it will connect to the FTP server to find that information).
{{HarFileSystem}} uses the URI of the har file itself as its home directory.
It doesn't make sense for these filesystems to use the same way of determining
their home directory that HDFS does. This is especially true for local
filesystems-- HDFS normally uses /user/foo, whereas local filesystems on UNIX
use /home/foo.
Since all these filesystems have a different way of setting their home
directory already, there is no point in adding a configuration key in common or
new methods to the FileSystem base class. Instead, let's just add a
configuration key to DFSConfigKeys that solves this specific problem.
