             Summary: upgrade-note.sh throws exception while upgrading notes on hdfs storage  
                 Key: ZEPPELIN-5112
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-5112
             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:
{code:java}
#!/bin/bash
export USE_HADOOP=true
{code}
