Hive Explode and extract a value from a String - sql

Question

Folks, I'm trying to extract value of 'status' from below string(column name: people) in hive. The problem is, the column is neither a complete JSON nor stored as an Array.
I tried to make it look like a JSON by replacing '=' with ':', which didnt help.
[{name=abc, org=true, self=true, status=accepted, email=abc#gmail.com}, {name=cab abc, org=false, self=false, status=needsAction, email=cab#google.com}]
Below is the query I used:
SELECT
str.name,
str.org,
str.status
FROM table
LATERAL VIEW EXPLODE (TRANSLATE(people,'=',':')) exploded as str;
but I'm getting below error:
FAILED: UDFArgumentException explode() takes an array or a map as a parameter
Need output something like this:
name | org | status
-------- ------- ------------
abc | true | accepted
cab abc | false | needsAction
Note: There is a table already, the datatype is string, and I
can't change the table schema.

Solution for Hive. It possibly can be optimized. Read comments in the code:
with your_table as ( --your data example, you select from your table instead
select "[{name=abc, org=true, self=true, status=accepted, email=abc#gmail.com}, {name=cab abc, org=false, self=false, status=needsAction, email=cab#google.com}]" str
)
select --get map values
m['org'] as org ,
m['name'] as name ,
m['self'] as self ,
m['status'] as status ,
m['email'] as email
from
(--remove spaces after commas, convert to map
select str_to_map(regexp_replace(a.s,', +',','),',','=') m --map
from your_table t --replace w your table
lateral view explode(split(regexp_replace(str,'\\[|\\{|]',''),'}, *')) a as s --remove extra characters: '[' or '{' or ']', split and explode
)s;
Result:
OK
true abc true accepted abc#gmail.com
false cab abc false needsAction cab#google.com
