JSON Data Read in Hive Table - json

Question

I am able to create Hive table using JSON Serde org.openx.data.jsonserde.JsonSerDe but when I am reading the data from Hive table I am unable to read.
hive> create table emp (EmpId int , EmpFirstName string , EmpLastName string) ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe';
OK
Time taken: 2.148 seconds
hive> LOAD DATA INPATH '/user/cloudera/EmpData/emp.json' INTO table emp;
Loading data to table employee.emp
chgrp: changing ownership of 'hdfs://quickstart.cloudera:8020/user/hive/warehouse/employee.db/emp/emp.json': User does not belong to supergroup
Table employee.emp stats: [numFiles=1, totalSize=4163]
OK
Time taken: 1.141 seconds
hive> select * from emp;
OK
Failed with exception java.io.IOException:org.apache.hadoop.hive.serde2.SerDeException: Row is not a valid JSON Object - JSONException: A JSONObject text must end with '}' at 2 [character 3 line 1]

Answer 1

ERROR: Failed with exception java.io.IOException:org.apache.hadoop.hive.serde2.SerDeException: Row is not a valid JSON Object - JSONException: A JSONObject text must end with '}' at 2 [character 3 line 1]
check the json provided in /user/cloudera/EmpData/emp.json is valid
You can eliminate the invalid row by
ALTER TABLE table emp SET SERDEPROPERTIES ( "ignore.malformed.json" = "true");
check this link -> https://github.com/rcongiu/Hive-JSON-Serde
Edit:
this is invalid json
{ "cols": [ "EmpId", "EmpFirstName", "EmpLastName" ], "data": [ [ 1, "Hannah", "Walton" ], [ 2, "Barrett", "Mendoza" ], [ 3, "Camden", "Kidd" ], [ 4, "Illiana", "Collier" ] ] }
the json provided by you has
key:cols and value:[ "EmpId", "EmpFirstName", "EmpLastName" ]
and
key :data and value :[ [ 1, "Hannah", "Walton" ], [ 2, "Barrett", "Mendoza" ], [ 3, "Camden", "Kidd" ], [ 4, "Illiana", "Collier" ]
the json should be something like
{"EmpId":1,"EmpFirstName":"Hannah","EmpLastName":"Walton"}
{"EmpId":2,"EmpFirstName":"Barrett","EmpLastName":"Mendoza"}
{"EmpId":3,"EmpFirstName":"Camden","EmpLastName":"Kidd"}
