Description

The following query fails with IOOB when a managed sort is used, but passes with the old default sort:

=========================================
0: jdbc:drill:zk=local> alter session set `exec.sort.disable_managed` = false;
------------------------------------------+

ok

summary

------------------------------------------+

true	exec.sort.disable_managed updated.

================================================

(the above query was extracted from /root/drillAutomation/framework-master/framework/resources/Functional/tpcds/variants/hive/q4_1.sql )

Note that the inlist must have at least 20 items, in which case the plan becomes a join over a stream-aggregate over a sort over the (inlist's) values. When the IOOB happens, the stack does not show the sort anymore, but probably handling a NONE returned by the last next() on the sort ( StreamingAggTemplate.doWork():182 )

The "date_dim" can probably be made up with any data. The one above was taken from:
[root@atsqa6c85 ~]# hadoop fs -ls /drill/testdata/tpcds/json/s1/date_dim
Found 1 items
-rwxr-xr-x 3 root root 50713534 2014-10-14 22:39 /drill/testdata/tpcds/json/s1/date_dim/0_0_0.json
