------------------------------------
Summary: NPE when the query runs successfully with empty result
set and error message refinement
Key: ZEPPELIN-3014
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3014
Project: Zeppelin
Issue Type: Bug
Components: Interpreters
Reporter: Jinxia Liu
Priority: Minor
When the sql query runs successfully, with empty result set, e.g. a select
query with zero rows returned, there would be NPE issue.
On the other hand, when the query fails, current kylin interpreter does not
expose the detailed error message the kylin server returns, need refine this
error message for better readability.
