We make extensive use of the elasticsearch-hadoop library for Hadoop/Spark. In trying to troubleshoot our Spark applications, it'd be very handy to have access to some of the many metrics <https://www.elastic.co/guide/en/elasticsearch/hadoop/current/metrics.html> that the library makes available when running in map reduce mode. The library's author noted <https://discuss.elastic.co/t/access-es-hadoop-stats-from-spark/44913> that Spark doesn't offer any kind of a similar metrics API where by these metrics could be reported or aggregated on.
Are there any plans to bring a metrics framework similar to Hadoop's Counter system to Spark or is there an alternative means for us to grab metrics exposed when using Hadoop APIs to load/save RDDs? Thanks, Mike
