------------------------------------
Hi Joel,
I think that I know what's the problem. In fact, this is an issue with the test
code as I see it. Let's look at one of error messages:
{code}
expected:<[hdfs://joe-desktop:49682]/test> but was:<[]/test>
{code}
If you look at the test code in {{TestLoad.java}},
{{hdfs://joe-desktop:49682/}} is supposed to be replaced by {{/}} as follows:
{code}
p.replaceAll("hdfs://[0-9a-zA-Z:\\.]*/", "/")
{code}
But it isn't. Why? Because your hostname {{joe-desktop:49682}} includes {{-}},
so it doesn't match the reg. exp. {{[0-9a-zA-Z:\\.]*}}.
So either you can change your hostname removing {{-}}, or you can fix the reg.
exp. so that your hostname can be matched. I would recommend to do the later.
Thanks!
