Description

git.commit.id.abbrev=522eb81

The data set used contains null values in the partition column. This causes the below query to fail with an NPE

create table fewtypesnull_varcharpartition partition by (varchar_col) as select * from dfs.`/drill/testdata/cross-sources/fewtypes_null.parquet`;
Error: SYSTEM ERROR: NullPointerException

Fragment 0:0

[Error Id: 6ef352c0-a12d-477c-bba8-e4a747a6b78e on qa-node190.qa.lab:31010] (state=,code=0)

I attached the data set and error log. Let me know if more information is needed
