Eli Collins updated HADOOP-8105:
--------------------------------
Description: The FilterFileSystem javadoc says "The class FilterFileSystem
itself simply overrides all methods of FileSystem with versions that pass all
requests to the contained file system." initialize(URI, Configuration) is part
of the FileSystem API, and before HADOOP-8013 it simply called fs.initialize().
After HADOOP-8013 it calls super.initialize() rather than delegating. This
breaks a number of the Hive tests. Hive's ProxyLocalFileSystem would be able to
work around this problem by calling setConf, but unfortunately FilterFileSystem
does not override that method. We need to make FilterFileSystem call
fs.initialize (instead of using super) and also override setConf. (was: The
