>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Execution - Relational Operators
>    Affects Versions: 1.6.0, 1.7.0, 1.8.0
>            Reporter: Karthikeyan Manivannan
>            Assignee: Karthikeyan Manivannan
>             Fix For: 1.9.0

>   Original Estimate: 2h
>  Remaining Estimate: 2h

> 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.
