Steve Loughran commented on HDFS-301:
-------------------------------------
This is going to be a fun patch to nurture through
* Some of the error handling is in
src/core/org/apache/hadoop/fs/FileSystem.java, in -common
* More error handling is in the Namenode, patches and testing go into -hdfs
I propose splitting the two
# -common code can have its own test, go into common
# Namenode patches can go in, test code moved to Junit4
The the second patch depends on the first, or at least its tests do; there's no
compile-time dependencies
> Provide better error messages when fs.default.name is invalid

> this the followon to HADOOP-5687 - its not enough to detect bad uris, we need
> good error messages and a set of tests to make sure everything works as
> intended.
