Amit Katti commented on DRILL-1058:
-----------------------------------
When I try to do the same with a different Json which has nested data in
addition to repeated data, it throws a different exception
(NullPointerException). In both cases, Drill is able to read the Json itself
perfectly.
The JSON looks like:
{"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" ],
"favorites": {"color": "Blue", "sport": "Soccer", "food": "Spaghetti"}}
QUERY: create table complex_student_tbl as select * from
`/user/root/drill/complex_student.json`;
ERROR MESSAGE:
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while

data_port: 31012
}
error_type: 0
message: "Screen received stop request sent. < NullPointerException"
]
Error: exception while executing query (state=,code=0)
The Exception in drillbit.log is:
