Alejandro Abdelnur commented on HDFS-3620:
------------------------------------------
If the target FS has home dirs in other location than '/user/<UID>' then
WebHdfsFileSystem will return the incorrect value.
To avoid perf issues, this call should be done ONCE per WebHdfsFilesystem and
cached in the instance.
> WebHdfsFileSystem getHomeDirectory() should not resolve locally
