> Tez - 0.5.0
> Hadoop - 2.5

> Following queries are representative of the exceptions we are seeing with trunk. These
queries pass if vectorization is disabled (or if limit is removed, which means no reducer).
> select name, log2(0) from (select name from mytable limit 1) t;
> select name, rand() from (select name from mytable limit 1) t;
> .. similar patterns with other Math UDFs'.
