             Summary: Select * after a join on a large data set results in an NPE
                 Key: DRILL-2278

I attached the data set which only contains 2 records. The below query works fine on this
data. However if we just copy over the same 2 records 50000 times, the same query fails with
an NPE.

{code}
select * from `data.json` t1 inner join `data.json` t2 on t1.uid=t2.uid;
Query failed: RemoteRpcException: Failure while running fragment.[ 1cec8b9a-5c04-44d8-b1a4-bcf3a0fadcbc
on qa-node190.qa.lab:31010 ]
[ 1cec8b9a-5c04-44d8-b1a4-bcf3a0fadcbc on qa-node190.qa.lab:31010 ]
{code}

Projecting a specific column works as expected.
