Subject [jira] [Resolved] (SPARK-5745) Allow to use custom TaskMetrics implementation
Date Sat, 09 Jan 2016 12:52:39 GMT


Sean Owen resolved SPARK-5745.
    Resolution: Won't Fix

> Allow to use custom TaskMetrics implementation
> ----------------------------------------------
>                 Key: SPARK-5745
>                 URL:
>             Project: Spark
>          Issue Type: Wish

> There can be various RDDs implemented and the {{TaskMetrics}} provides a great API for
collecting metrics and aggregating them. However some RDDs may want to register some custom
metrics and the current implementation doesn't allow for this (for example the number of read
rows or whatever).
> I suppose that this can be changed without modifying the whole interface - there could
used some factory to create the initial {{TaskMetrics}} object. The default factory could
be overridden by user.
