incubator-drill git commit: DRILL-1455: enable projection pushdown
past join
Repository: incubator-drill
Updated Branches:
refs/heads/master d5b9b11c9 -> 66cf6e274
DRILL-1455: enable projection pushdown past join
i) refactor project past filter to remove redundant code
ii) adding unit tests for projection past join & hybrid cases like projection past filter & join
iii) disable one TestExampleQueries#testSelectStartSubQueryJoinWithWhereClause until DRILL-1680 is fixed.
