This will require a bit more effort to fix, since we'll either have to find a way to use a fixed size / capped size encoding for MapOutputStatuses (which might require changes to let us fetch empty blocks safely) or figure out some other strategy for shipping these statues. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
