The following Mondrian query hangs. It was working with previous release.

0: jdbc:drill:schema=dfs>
SELECT time_by_day.the_year     AS c0, 
       time_by_day.quarter      AS c1, 
       store.store_state        AS c2, 
       FACT.warehouse_id        AS c3, 
       Sum(FACT.warehouse_cost) AS m0 
FROM   time_by_day AS time_by_day, 
       (SELECT * 
        FROM   inventory_fact_1997 AS FOOBAR) AS FACT, 
       store AS store 
WHERE  FACT.time_id = time_by_day.time_id 
       AND time_by_day.the_year = 1997 
       AND time_by_day.quarter = 'Q3' 
       AND FACT.store_id = store.store_id 
       AND store.store_state = 'WA' 
       AND FACT.warehouse_id = 2 
GROUP  BY time_by_day.the_year, 

The drillbit handles the query seems active with around 100% CPU usage but the query never
returns. The only log message found in drill bit.log is following:

2014-11-13 15:07:14,426 [UserServer-1] WARN  o.a.d.exec.work.foreman.QueryStatus - Update
running or pending query state : PENDING

Since this is a regression, marked as release blocker.
