Convert Json to separate columns in HIVE - json

Question

I have 4 columns in Hive database table. First two columns are of type string, 3rd and 4th are of JSON. Type. How to extract json data in different columns.
SERDE available in Hive seems to be handling only json data. I have both normal (STRING) and JSON data. How can I extract data in separate colums here.
Example:
abc 2341 {max:2500e0,value:"20",Type:"1",ProviderType:"ABC"} {Name:"ABC",minA:1200e0,StartDate:1483900200000,EndDate:1483986600000,Flags:["flag4","flag3","flag2","flag1"]}
xyz 6789 {max:1300e0,value:"10",Type:"0",ProviderType:"foo"} {Name:"foo",minA:3.14159e0,StartDate:1225864800000,EndDate:1225864800000,Flags:["foo","foo"]}

Answer 1

Given a fixed JSON
create table mytable (str string,i int,jsn1 string, jsn2 string);
insert into mytable values
('abc',2341,'{"max":2500e0,"value":"20","Type":"1","ProviderType":"ABC"}','{"Name":"ABC","minA":1200e0,"StartDate":1483900200000,"EndDate":1483986600000,"Flags":["flag4","flag3","flag2","flag1"]}')
,('xyz',6789,'{"max":1300e0,"value":"10","Type":"0","ProviderType":"foo"}','{"Name":"foo","minA":3.14159e0,"StartDate":1225864800000,"EndDate":1225864800000,"Flags":["foo","foo"]}')
;
select str,i
,jsn1_max,jsn1_value,jsn1_type,jsn1_ProviderType
,jsn2_Name,jsn2_minA,jsn2_StartDate,jsn2_EndDate
,jsn2_Flags
from mytable
lateral view json_tuple (jsn1,'max','value','Type','ProviderType')
j1 as jsn1_max,jsn1_value,jsn1_type,jsn1_ProviderType
lateral view json_tuple (jsn2,'Name','minA','StartDate','EndDate','Flags')
j2 as jsn2_Name,jsn2_minA,jsn2_StartDate,jsn2_EndDate,jsn2_Flags
;
