Tim Armstrong reopened IMPALA-10102:
------------------------------------
[~baggio000] Impala still shouldn't crash if there isn't enough memory, it
should return a clean error to the user and not disrupt other running queries.
So I'm going to reopen this.

> Encountered a crash when testing following queries on my local branch:
> {code:sql}
> create table bigstrs3 stored as parquet as
> select *, repeat(uuid(), cast(random() * 200000 as int)) as bigstr
> from functional.alltypes
> limit 1000;
> # Length of uuid() is 36. So the max row size is 7,200,000.
> set MAX_ROW_SIZE=8m;
> create table my_str_group stored as parquet as
> select group_concat(string_col) as ss, bigstr
> from bigstrs3 group by bigstr;
> create table my_cnt stored as parquet as
> select count(*) as cnt, bigstr
