Sorabh Hamirwasia updated DRILL-6694: ------------------------------------- Labels: ready-to-commit (was: ) > NPE in UnnestRecordBatch when query uses a column name not present in data > -------------------------------------------------------------------------- > > Key: DRILL-6694 > URL: https://issues.apache.org/jira/browse/DRILL-6694 > Project: Apache Drill > Issue Type: Bug > Components: Execution - Relational Operators > Affects Versions: 1.14.0 > Reporter: Sorabh Hamirwasia > Assignee: Sorabh Hamirwasia > Priority: Major > Labels: ready-to-commit > Fix For: 1.15.0 > > > When the array column name doesn't exist in the underlying data and is used > in query with Unnest then there is NPE. The reason is Unnest tries to get the > ValueVector of unnest column from incoming based on TypedFieldId which will > be null in this case and hence the exception. > {code:java} > [Error Id:
