lateral view explode in impala?

[#1]

I have data as source as below. How to transform the multi rows?

Any function like lateral view explode in impala?

[#2]

We don't support this in Impala right now. We'd generally recommend using Hive to prepare such data for querying.

[#3]

Is it supported now?

[#4]

Do we have any alternative for this to do in impala or introduced any function to support in any newer version of impala?

Thanks

There is a workaround to solve this. Is not a definitive solutions but it can help:

The final result would be like this: 

• Firstly, I created a table like your example (I used ";" as separator):

insert overwrite t_1
select 'Asia' as cont,'Japan;China;Singapore;' Country_list union
select 'Europe' as cont,'UK;Spain;Italy;German;Norway;' Country_list

• After, I created a external table. It must be stored as textfile:

CREATE EXTERNAL TABLE IF NOT EXISTS t_transpose (
field_transpose string
)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ";"
STORED AS TEXTFILE;

• Then insert on this table like this:

insert overwrite t_transpose
select REGEXP_REPLACE(Country_list, ';', concat("|", cont, '\n' ) ) as transpose
from t_1;

• After you can select like in my example before: 

 select split_part(field_transpose,"|",1), split_part(field_transpose,"|",2) from t_transpose;

Ps: The final result could have some blank lines, just filter/ignore it. I also put one more ";" in the line comparing with the example informed.
