Description

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.
