Thanks, Akhil. I had high hopes for #2, but tried all and no luck.
I was looking at the source and found something interesting. The Stack
Trace (below) directs me to FileInputDStream.scala (line 141). This is
version 1.1.1, btw. Line 141 has:
private def fs: FileSystem = {
> if (fs_ == null) fs_ = directoryPath.getFileSystem(new Configuration())
> fs_
> }
So it looks to me like it doesn't make any attempt to use a configured
HadoopConf.
Here is the StackTrace:
