Subject [jira] [Commented] (SPARK-1529) Support setting spark.local.dirs to a hadoop FileSystem
Date Wed, 07 Jan 2015 08:51:34 GMT


Patrick Wendell commented on SPARK-1529:

BTW - I think if MapR wants to have a customized shuffle, the direction proposed in this patch
is probably not the best way to do it. It would make more sense to implement a DFS-based shuffle
using the new pluggable shuffle API. I.e. a shuffle that communicates through the filesystem
rather than doing transfers through Spark.

> In some environments, like with MapR, local volumes are accessed through the Hadoop filesystem
interface. We should allow setting spark.local.dir to a Hadoop filesystem location.
