[jira] [Created] (SPARK-4183) Enable Netty-based BlockTransferService by default

Aaron Davidson created SPARK-4183:

             Summary: Enable Netty-based BlockTransferService by default
                 Key: SPARK-4183
                 URL: https://issues.apache.org/jira/browse/SPARK-4183
             Project: Spark
          Issue Type: Bug
            Reporter: Aaron Davidson
            Assignee: Aaron Davidson


Spark's NettyBlockTransferService relies on Netty to achieve high performance and zero-copy IO, which is a big simplification over the manual connection management that's done in today's NioBlockTransferService. Additionally, the core functionality of the NettyBlockTransferService has been extracted out of spark core into the "network" package, with the intention of reusing this code for SPARK-3796 ([PR #3001|https://github.com/apache/spark/pull/3001/files#diff-54]).

We should turn NettyBlockTransferService on by default in order to improve debuggability and stability of the network layer (which has historically been more challenging with the current BlockTransferService).
