Review request for hive and Ashutosh Chauhan. Repository: hive-git Description ------- Right now StatsOptimizer can deal with query such as "select count(1) from src" by directly looking into the metastore. However, it can not deal with "select '1' as one, count(1) from src" which has an additional constant column. We may improve it. Diffs ----- ql/src/java/org/apache/hadoop/hive/ql/optimizer/StatsOptimizer.java bc8d8f7 ql/src/test/queries/clientpositive/metadata_only_queries.q 56f3a78 ql/src/test/results/clientpositive/metadata_only_queries.q.out 2dcd437 Diff: https://reviews.apache.org/r/38690/diff/ Testing ------- Thanks, pengcheng xiong
