Description

In attempting to run the extended test suite provided by MapR, there are a large number of queries that fail due to issues in the PruneScanRule and specifically the DFSPartitionLocation constructor line 31. It is likely due to issues with the code that are related to running on HDFS where this code path has apparently not been tested.

An example test query this type of failure occurred:

/src/drill-test-framework/resources/Functional/ctas/ctas_auto_partition/tpch0.01_multiple_partitions/data/q11.q

Example stack trace below:
