Subject [jira] [Created] (DRILL-4974) NPE in FindPartitionConditions.analyzeCall() for 'holistic' expressions
Date Thu, 27 Oct 2016 18:25:59 GMT

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

             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.
