Major Description
repro:
Create some hive tables having datatypes which are valid in drill. Ie no struct, arrays etc.
Select * from INFORMATION_SCHEMA.TABLES works at this point.
Create a hive table containing complex data types: Example:
CREATE TABLE test_serializer(string1 STRING,
int1 INT,
tinyint1 TINYINT,
smallint1 SMALLINT,
bigint1 BIGINT,
boolean1 BOOLEAN,
float1 FLOAT,
double1 DOUBLE,
list1 ARRAY<STRING>,
map1 MAP<STRING,INT>,
struct1 STRUCT<sint:INT,sboolean:BOOLEAN,sstring:STRING>,
enum1 STRING,
nullableint INT,
bytes1 BINARY,
fixed1 BINARY)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' COLLECTION ITEMS TERMINATED BY ':' MAP KEYS TERMINATED BY '#' LINES TERMINATED BY '\n'
STORED AS TEXTFILE;
After this INFORMATION_SCHEMA queries fail with
message: "Failure while parsing sql. < ValidationException:[ java.lang.RuntimeException: Unknown or unsupported hive type ] < RuntimeException:[ Unknown or unsupported hive type ]"
