We have Accumulo 1.6.3 set up on the HortonWorks install with a basic
cluster of one master and one tablet server. Initially everything seemed good
but now I'm getting a NullPointerException when I go to the monitor web page.
The logs also keep adding a message to that effect as well. I searched and
couldn't find any posts with the same problem. I went back through all of the
config files and made sure they conform to the configuration instructions.
I'm hoping someone can point me to the right place to look for
troubleshooting.
