Commit 7dd4799235619eb8bba35b6aed65b8b4d8b6f113 in
incubator-asterixdb-hyracks's branch refs/heads/master from [~buyingyi]

Fix for ASTERIXDB-1018, ASTERIXDB-1017, ASTERIXDB-1019,
ASTERIXDB-1020, ASTERIXDB-1029, ASTERIXDB-1030, ASTERIXDB-1034:
1. Let the keys of introduced nested group-bys (group-bys in a subplan) be only
the
variables that are produced in the subplan;
2. In PushSelectIntoJoinRule, push independent operators (e.g., a
current-datetime() call)
into the first branch from which the join condition refers some variables.
3. In SimpleUnnestToJoinRule, move the boundary between the two join branches
of a added join
which results from pipelined datascans to be below operators that doesn't use
any variables
(e.g., a current-datetime() call), therefore potentially, the upper (left) join
branch
can be rewritten to index lookups.
