> The logic during vectorized execution that keeps track of how deep we are in the nested
structure doesn't work for ARRAYs and STRUCTs embedded inside maps.
> Repro steps (with hive.vectorized.execution.enabled=true):
> {code}
> CREATE TABLE srctable(a map<int,array<int>>) STORED AS TEXTFILE;
> create table desttable(c1 map<int,array<int>>);
> insert into srctable values (map(1, array(1, 2, 3)));
> insert into desttable select a from srctable;
> select * from desttable;
> {code}
> Will produce:
> {code}
> {1:[null]}
> {code}
