From 1ae51f6dc7e79a88dfe54a2c488b540fdbf51212 Mon Sep 17 00:00:00 2001 From: Aaron Davidson Date: Sat, 1 Nov 2014 13:15:24 -0700 Subject: [SPARK-4183] Enable NettyBlockTransferService by default Note that we're turning this on for at least the first part of the QA period as a trial. We want to enable this (and deprecate the NioBlockTransferService) as soon as possible in the hopes that NettyBlockTransferService will be more stable and easier to maintain. We will turn it off if we run into major issues.
