-------------------------------------

             Summary: Explicit cast of empty string to double/integer throws NumberFormatException

                 Key: DRILL-986
                 URL: https://issues.apache.org/jira/browse/DRILL-986
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Data Types
            Reporter: Abhishek Girish


While running TPC-DS queries we hit an issue while reading Parquet. When narrowed down, it
was seen to be an issue with explicit cast when data files consist of null/empty strings.


SqlLine error:
