Review request for hive and Xuefu Zhang. 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 ----- 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
