DRILL WRITING A PARQUET TABLE WITH NESTED DATA
=================================================
I have a JSON file with nested data (schema present below):

{"rownum":1,"name":"fred ovid","age":76,"gpa":1.55,"studentnum":692315658449,"create_time":"2014-05-27 00:26:07", "interests": [ "Reading", "Mountain Biking", "Hacking" ]}

I am able to read this JSON file successfully from drill and access nested values. However when I try to import this data and create a table in PARQUET format, it errors:

QUERY: create table test as select * from `/user/root/sample-data/nested_student.json`;

ERROR: Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while running query.[error_id: "3ce3dc1e-d920-4262-ae2d-28bd2d034597"

DRILL READING A PARQUET TABLE WITH NESTED DATA
=================================================
I generated a parquet file by reading the below Json file into pig and storing it in a parquet format:
{"recipe":"Tacos","ingredients":[

{"name":"Beef"}

{"name":"Lettuce"}

{"name":"Cheese"}

],"inventor":{"name":"Alex","age":25}}
{"recipe":"TomatoSoup","ingredients":[

{"name":"Tomatoes"}

{"name":"Milk"}

],"inventor":{"name":"Steve","age":23}}

When I try to read this parquet table in Drill, it errors:

QUERY: Select * from `/user/root/complex.parquet`;

ERROR: Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while running query.[error_id: "c2e735f4-e11c-4e10-a410-959b3880dce0"
