Github user pwendell commented on a diff in the pull request: https://github.com/apache/spark/pull/3107#discussion_r20060444 --- Diff: docs/configuration.md --- @@ -563,8 +566,8 @@ Apart from these, the following properties are also available, and may be useful </ul> </td> <td> - Default number of tasks to use across the cluster for distributed shuffle operations - (<code>groupByKey</code>, <code>reduceByKey</code>, etc) when not set by user. + Default number of output partitions for operations like <code>join</code>, --- End diff -- Should this say "number of shuffle partitions" - it's slightly weird to me to say "output" when this refers to something that is totally internal to Spark - it's output on the map side but input on he read side. In other cases I think output tends to mean things like saving as HDFS data, etc.
