Hello Tim Armstrong, Impala Public Jenkins, Vuk Ercegovac,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/11556
to look at the new patch set (#4).
Change subject: IMPALA-6323 Allow constant analytic window expressions.
......................................................................
IMPALA-6323 Allow constant analytic window expressions.
The constraint imposed by IMPALA-1354 was artificial.
If there are constant "partition by" expressions, simply drop them,
they are no-ops.
Constant "order by" expressions can be ignored as well, though in effect
they should be accounted for as null expressions in the backend, with the
effect that combine all rows in the same window (i.e. no window breaks).
