--------------------------------------

             Summary: Attempt to enable interpreter recovery causes errors
                 Key: ZEPPELIN-4648
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4648
             Project: Zeppelin
          Issue Type: Bug
            Reporter: Paul Brenner


Zeppelin is extremely unstable for our use cases (ZEPPELIN-4599). I'd like to try interpreter recovery as described here: [https://medium.com/@zjffdu/zeppelin-0-8-0-new-features-ea53e8810235].

I added 
{code:java}
<property>
  <name>zeppelin.recovery.storage.class</name>
  <value>org.apache.zeppelin.interpreter.recovery.FileSystemRecoveryStorage</value>
  <description>ReoveryStorage implementation</description>
</property><property>
  <name>zeppelin.recovery.dir</name>
  <value>/opt/zeppelin/recovery</value>
  <description>Location where recovery metadata is stored</description>
</property>
{code}
to zeppelin-site.xml then attempted to start zeppelin (0.9 built from source and 0.82 packaged version). When zeppelin starts up I can no longer log in and get the errors shown in the following logs (these are clean and only show the messages since starting with recovery enabled). Any idea what is wrong? I haven't seen any posts from people using recovery.
