[jira] [Created] (ZEPPELIN-789) Skip execution of a paragraph in case of error

Prasad Krishnan (Jira)
Samuel Alexander created ZEPPELIN-789:
-----------------------------------------

             Summary: Skip execution of a paragraph in case of error
                 Key: ZEPPELIN-789
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-789
             Project: Zeppelin
          Issue Type: Improvement
          Components: zeppelin-zengine
    Affects Versions: 0.6.0
            Reporter: Samuel Alexander
             Fix For: 0.6.0


When a notebook is executed all the paragraphs in the notebook will get executed. In many cases result of one paragraph will be use in next subsequent paragraphs. For example, we may load a dataframe in one of the paragraph which will be used in all subsequent paragraphs.

In this case, if loading of dataframe is failed, execution of the remaining paragraphs has no meaning. So we need to have option in paragraph to skip execution if any of the paragraphs that were executed before results in error.

In our case, we can have this option 'skipOnError' too true to the paragraph which uses dataframe constructed from previous paragraph. So execution will be skipped if dataframe is not loaded.
