> We have noticed that the JsonSerde produces a NullPointerException if a JSON object has a key value that is not lower case. For example. Assume we have the file "one.json": 
> { "empId" : 123, "name" : "John" } 
> { "empId" : 456, "name" : "Jane" } 
> hive> CREATE TABLE emps (empId INT, name STRING) 
> ROW FORMAT SERDE "org.apache.hive.hcatalog.data.JsonSerDe"; 
> hive> LOAD DATA LOCAL INPATH 'one.json' INTO TABLE emps; 
> hive> SELECT * FROM emps; 
> Failed with exception java.io.IOException:java.lang.NullPointerException 
> -------- 
> Notice, it seems to work if the keys are lower case. Assume we have the file 'two.json': 
> { "empid" : 123, "name" : "John" } 
> { "empid" : 456, "name" : "Jane" } 
> hive> DROP TABLE emps; 
> hive> CREATE TABLE emps (empId INT, name STRING) 
> ROW FORMAT SERDE "org.apache.hive.hcatalog.data.JsonSerDe"; 
> hive> LOAD DATA LOCAL INPATH 'two.json' INTO TABLE emps;
> hive> SELECT * FROM emps; 
> OK 
> 123	John 
> 456	Jane
