Hi folks, I'm having trouble migrating a large number of notebooks from Zeppelin 0.7.3 to 0.9.0-preview1. I followed the instructions from the website, i.e., downloading the latest release (0.9.0-preview1) and then copying the conf/ and notebook/ over to override these two directories in the new one. I'm able to start the Zeppelin, but when I access the home page, I encounter the following errors (listed at the end).
I also tried to export the notebook json from 0.7.3 and import that json file to 0.9.0-preview1. When I open it in the page, the notebook paragraphs don't show up and the page is completely blank except for the notebook caption. The notebook I create directly in 0.9.0-preview1 can be shown properly. Any suggestion on how to properly batch migrate the notebooks in this case? Any input would be appreciated.
