[jira] [Updated] (SAMZA-409) hello-samza's wikipedia-stats job won't start

     [ https://issues.apache.org/jira/browse/SAMZA-409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Martin Kleppmann updated SAMZA-409:
-----------------------------------
    Attachment: SAMZA-409.patch

Adding a checkpoint manager to wikipedia-stats exposes another error:

Exception in thread "main" java.lang.ClassNotFoundException: org.apache.samza.storage.kv.KeyValueStorageEngineFactory

Attaching a patch which fixes both issues.

> Since SAMZA-123, the wikipedia-stats job in hello-samza fails on startup with the following error:
> org.apache.samza.SamzaException: Storage factories configured, but no checkpoint manager has been specified.  Unable to start job as there would be no place to store changelog partition mapping.
