[jira] [Created] (IMPALA-5973) Provide query plan in JSON format

Alexander Behm created IMPALA-5973:
--------------------------------------

             Summary: Provide query plan in JSON format
                 Key: IMPALA-5973
                 URL: https://issues.apache.org/jira/browse/IMPALA-5973
             Project: IMPALA
          Issue Type: New Feature
          Components: Frontend
    Affects Versions: Impala 2.10.0
            Reporter: Alexander Behm


Today there is only a text representation of the query plan, but it would be useful to have a JSON version for portability and machine consumption.

To control whether EXPLAIN should produce a text or JSON output we could augment the EXPLAIN syntax or we could introduce a query option. It's worth discussing which one makes more sense.

Internally our code should always generate the JSON plan, and then have a function that can convert the JSON plan to the conventional textual representation.
