Hive generated parquet files with maps containing strings return wrong value

Created a parquet file in hive having the following DDL
hive> desc alltypesparquet;
OK
c1 int
c2 boolean
c3 double
c4 string
c5 array<int>
c6 map<int,string>
c7 map<string,string>
c8 struct<r:string,s:int,t:double>
c9 tinyint
c10 smallint
c11 float
c12 bigint
c13 array<array<string>>
c15 struct<r:int,s:struct<a:int,b:string>>
c16 array<struct<m:map<string,string>,n:int>>
Time taken: 0.076 seconds, Fetched: 15 row(s)

All the complex types with string in them are returning incorrect values in drill. For example:

hive> select c6 from alltypesparquet;
NULL
NULL

0: jdbc:drill:> select c6 from `/user/hive/warehouse/alltypesparquet`;
