ATTACHMENT ID: 12681594 - PreCommit-HIVE-SPARK-Build
> Print prettier Spark work graph after HIVE-8793 [Spark Branch]
> --------------------------------------------------------------
>
> Key: HIVE-8840
> URL: https://issues.apache.org/jira/browse/HIVE-8840
> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Xuefu Zhang
> Assignee: Jimmy Xiang
> Fix For: spark-branch
>
> Attachments: HIVE-8840.1-spark.patch, HIVE-8840.2-spark.patch
>
>
> Because of HIVE-8793, the work graph for Spark is possibly modified by
> SplitSparkWorkResolver. Original:
> {code}
> Spark
> Edges:
> Reducer 2 <- Map 1 (SORT, 1)
> Reducer 3 <- Reducer 2 (GROUP, 1)
> Reducer 4 <- Reducer 2 (GROUP, 1)
> {code}
> New graph
> {code}
> Spark
> Edges:
> Reducer 3 <- Reducer 5 (GROUP, 1)
> Reducer 4 <- Reducer 6 (GROUP, 1)
> Reducer 5 <- Map 1 (SORT, 1)
> Reducer 6 <- Map 1 (SORT, 1)
> {code}
> where Reducer2 was splitted into Reducer5 and Reducer6.
> Two types of ordering can be considered:
> 1. Topological order
> {code}
> Spark
> Edges:
> Reducer 5 <- Map 1 (SORT, 1)
> Reducer 6 <- Map 1 (SORT, 1)
> Reducer 3 <- Reducer 5 (GROUP, 1)
> Reducer 4 <- Reducer 6 (GROUP, 1)
> {code}
> 2. DFS
> {code}
> Spark
> Edges:
> Reducer 5 <- Map 1 (SORT, 1)
> Reducer 3 <- Reducer 5 (GROUP, 1)
> Reducer 6 <- Map 1 (SORT, 1)
> Reducer 4 <- Reducer 6 (GROUP, 1)
> {code}
> Both seems better, though topolical seems more suitable for a graph. Please
> feel free to create a patch on trunk if needed.
