---------------------------------------------
Summary: NPE in FindPartitionConditions.analyzeCall() for
'holistic' expressions
Key: DRILL-4974
URL: https://issues.apache.org/jira/browse/DRILL-4974
Project: Apache Drill
Issue Type: Bug
Components: Execution - Relational Operators
Affects Versions: 1.8.0, 1.7.0, 1.6.0
Reporter: Karthikeyan Manivannan
Assignee: Karthikeyan Manivannan
Fix For: 1.8.0
The following query can cause an NPE in FindPartitionConditions.analyzeCall()
if the fileSize column is a partitioned column.
SELECT fileSize FROM dfs.`/drill-data/data/` WHERE compoundId LIKE
'FOO-1234567%'
This is because, the LIKE is treated as a holistic expression in
FindPartitionConditions.analyzeCall(), causing opStack to be empty, thus
causing opStack.peek() to return a NULL value.
