INSERT..SELECT Fails "Error Code: 1815. Internal error"

use test;

create table test1_cs (id int,cName varchar(50)) engine=columnstore;

– This statement works as expected
insert into test1_cs(id,cName) values(1,'Testing1');

– Thist statement does not work.
insert into test1_cs (id,cName)
select 2,'Testing2';

– Results in following error
/*
Error Code: 1815. Internal error: load failed. The detailed error information is listed in err.log.
*/

Is this a bug or do I need to enable some flag?

We are not able to transfer data from one columnstore table to another and worst yet from staging innodb table to columnstore table. Currently we have written a work around to use CPIMPORT tool. This is certainly slowing down our pipeline and testing.
