Subject possible hicc problems?
Date Fri, 22 May 2009 03:52:38 GMT
Howdy all.

So I now have HICC displaying Hadoop metrics (yay!)

But it seems to work wonkily.  I was messing around with adding new
things to display, and wound up injuring hicc somehow.  Symptom: a
whole bunch of graphs refuse to display, just drawing whitespace.
And intead of showing actual machine names, the host selector widget
has HTTP escapes around the names.
So "hostname" got replaced with  %22hostname%22.  Why?

I had the following in my catalina.out:
