    Description

      Parent build: http://sandbox.jenkins.cloudera.com/job/impala-cdh5-trunk-exhaustive-release/39/?
      Hung build: http://sandbox.jenkins.cloudera.com/job/impala-umbrella-build-and-test/596/? (still running as of this posting)

      According to the debug webpage, it's hung on this query:

      select cast(floor(id/3) as int), tinyint_col, first_value(tinyint_col)
      over (partition by cast(floor(id/3) as int) order by tinyint_col nulls first),
      first_value(cast(tinyint_col as string))
      over (partition by cast(floor(id/3) as int) order by cast(tinyint_col as string) nulls first),
      last_value(tinyint_col)
      over (partition by cast(floor(id/3) as int) order by tinyint_col nulls first),
      last_value(cast(tinyint_col as string))
      over (partition by cast(floor(id/3) as int) order by cast(tinyint_col as string) nulls first)
      from alltypesagg
      where id < 50 and (tinyint_col is null or tinyint_col < 4)
