-----------------------------------
Description:
When applying partitions in TestValuesScanTableSourceWithoutProjectionPushDown
with no partition provided, the following code will cause ClassCastException
{code:java}
remainingPartitions = (List<Map<String, String>>) Collections.emptyMap();
this.data.put(Collections.emptyMap(), Collections.emptyList());
{code}
{code:java}
java.lang.ClassCastException: java.util.Collections$EmptyMap cannot be cast to
java.util.List
