> CBO fails on multi insert overwrites with common group expression

> The following statement is failing in CBO:
>
> {code:java}
> FROM (select key, f1 FROM tbl1 where key=5) a
> INSERT OVERWRITE TABLE tbl2 partition(key=5)
> select f1 WHERE key > 0 GROUP by f1
> INSERT OVERWRITE TABLE tbl2 partition(key=6)
> select f1 WHERE key > 0 GROUP by f1;
> {code}
> The failure happens when there is a filter to a constant value in the FROM
> clause ,the value is referenced in the filter in the INSERT OVERWRITE, and
> there is a common group existing across the insert overwrites.
> CBO is pulling up the key = 5 expression into the select clause as a constant
> (i.e. select 5 key, f1 FROM tbl1 where key = 5). After it gets converted
> back into AST and then re-compiled, there is code in the common group method
> that expects all columns to be non-constants which is causing the failure.
> The failure stacktrace is shown below:
