--------------------------------
Attachment: HIVE-18368.1.patch
> Improve Spark Debug RDD Graph
> -----------------------------
>
> Key: HIVE-18368
> URL: https://issues.apache.org/jira/browse/HIVE-18368
> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Sahil Takiar
> Assignee: Sahil Takiar
> Attachments: HIVE-18368.1.patch, Spark UI - Named RDDs.png
>
>
> The {{SparkPlan}} class does some logging to show the mapping between
> different {{SparkTran}}, what shuffle types are used, and what trans are
> cached. However, there is room for improvement.
> When debug logging is enabled the RDD graph is logged, but there isn't much
> information printed about each RDD.
> We should combine both of the graphs and improve them. We could even make the
> Spark Plan graph part of the {{EXPLAIN EXTENDED}} output.
> Ideally, the final graph shows a clear relationship between Tran objects,
> RDDs, and BaseWorks. Edge should include information about number of
> partitions, shuffle types, Spark operations used, etc.
