Subject [jira] [Commented] (HDFS-4705) TestAllowFormat fails on Windows because of invalid dfs.namenode.name.dir

Ivan Mitic commented on HDFS-4705:
----------------------------------

Hey Chris, no worries at all, and thanks for attaching the patch!

I started with a similar approach to yours and then saw the other test failures, so I thought
it is worth to spent some time seeing if it makes sense to fix them all at ones.

I was thinking along the lines of changing {{Util#fileAsURI}} such that it converts the given
File to Path and then from Path to the URI. However, on top of this we'd also have to change
the default value for {{dfs.namenode.name.dir}} as "file://$hadoop.tmp.dir/dfs/name" is actually
not a valid local URI (there should 3 forward slashes after "file:", IOW: "file:///$hadoop.tmp.dir/dfs/name").
I haven't tested this out, so it might be that there are some problems here.

You're welcome to take this up if you want :)
