             Summary: throw NPE or AssertionError in FindPartitionConditions 
when running some SQLs on partition table
                 Key: DRILL-4889
                 URL: https://issues.apache.org/jira/browse/DRILL-4889
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.8.0
            Reporter: godfrey he


when I ran some SQLs on partition table, I got NPE or AssertionError in 
FindPartitionConditions 

partition_table is a partition table
partition_column is the partition column
none_partition_column is a normal column, not the partition column

SQL 1: select * from partition_table where none_partition_column like '%test%'; 
and also
SQL 2:  select * from partition_table where case when partition_column = '2000' 
then none_partition_column = 'test' end;

Caused by: java.lang.NullPointerException: null

SQL 3: select * from partition_table where partition_column = 'a' or 
(partition_column = 'b' and partition_column = '2000')
