--------------------------------------
Summary: Missing dependencies array in interpreter.json after
upgrade from 0.6.2 to 0.7.0
Key: ZEPPELIN-2124
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2124
Project: Zeppelin
Issue Type: Bug
Components: conf
Affects Versions: 0.7.0
Reporter: Frank Rosner
h4. Problem
We upgraded our Zeppelin instance from 0.6.2 to 0.7.0 today and after that we
were not able to add any new dependencies to the interpreters.
The JS console revealed that {{a.dependencies is undefined}}. This happens
because the interpreter configuration ({{interpreter.json}} now has to contain
a {{dependencies}} array, which was not the case in 0.6.2.
After adding {{dependencies: [],}} to {{interpreter.json}} it is working just
fine.
h4. Solution
If the {{dependencies}} array is not present it should either assume that it is
empty or fail fast. It should not throw invisible errors in JavaScript.
