Subject [jira] [Commented] (SPARK-2868) Support named accumulators in Python
Date Fri, 07 Oct 2016 23:24:20 GMT

holdenk commented on SPARK-2868:
--------------------------------

Is this something we are still interested in pursuing (cc [~rxin] who did the Scala accumulator
API update). I'd be happy to take on this issue, once we've decide what to do around data
property accumulators, since I've already been working with accumulators a bunch.

> SPARK-2380 added this for Java/Scala. To allow this in Python we'll need to make some
additional changes. One potential path is to have a 1:1 correspondence with Scala accumulators
(instead of a one-to-many). A challenge is exposing the stringified values of the accumulators
to the Scala code.
