[SPARK-17880][DOC] The url linking to `AccumulatorV2` in the document is incorrect. ## What changes were proposed in this pull request? In `programming-guide.md`, the url which links to `AccumulatorV2` says `api/scala/index.html#org.apache.spark.AccumulatorV2` but `api/scala/index.html#org.apache.spark.util.AccumulatorV2` is correct. ## How was this patch tested? manual test. Author: Kousuke Saruta <saru...@oss.nttdata.co.jp> Closes #15439 from sarutak/SPARK-17880.

The AccumulatorV2 abstract class has several methods which need to override: `reset` for resetting the accumulator to zero, and `add` for add anothor value into the accumulator, `merge` for merging another same-type accumulator into this one. Other methods need to override can refer to scala API document. For example, supposing we had a `MyVector` class representing mathematical vectors, we could write: --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@spark.apache.org For additional commands, e-mail: commits-h...@spark.apache.org
