Description

When I ran some SQLs on partition table, I got NPE or AssertionError in FindPartitionConditions as below:

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%';
SQL 2: select partition_column from partition_table where none_partition_column like '%test%';
SQL 3: select * from partition_table where case when partition_column = '2000' then none_partition_column = 'test' end;
