(Updated Sept. 29, 2014, 8:16 p.m.) Review request for hive and Xuefu Zhang. Changes ------- Updated according to Xuefu's suggestions. Bugs: HIVE-8278 https://issues.apache.org/jira/browse/HIVE-8278 Repository: hive-git Description ------- HIVE-8249 greatly simply file the SparkPlan model and the SparkPlanGenerator logic. As a side effect, however, a visual representation of SparkPlan got lost. Such representation is helpful for debugging and performance profiling. In addition, it would be also good to separate plan generation and plan execution. Diffs (updated) ----- ql/src/java/org/apache/hadoop/hive/ql/exec/spark/SparkPlan.java f8b3283 ql/src/java/org/apache/hadoop/hive/ql/exec/spark/SparkPlanGenerator.java 15af0f9 Diff: https://reviews.apache.org/r/26120/diff/ Testing ------- Thanks, Chao Sun
