Summary: upgrade-note.sh throws exception while upgrading notes on

Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.9.0
Reporter: Anchal Agarwal
With zeppelin version 0.9.0-preview2, I'm able to read, write and execute new
notebooks. But while trying to upgrade existing notes from version 0.8.1 to
version 0.9.0-preview2, I get this exception when I run bin/upgrade-note.sh:
{code:java}

I'm storing notebooks on hdfs and my zeppelin-env.sh has the required env
variable:

#!/bin/bash
export USE_HADOOP=true
