Patrick Wendell reopened SPARK-4183: ------------------------------------ Reverted this due to a test issue - seems like some state is not getting cleaned up. > 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 > Fix For: 1.2.0 > > > 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
