Colin Patrick McCabe commented on HDFS-9805: -------------------------------------------- Thanks for the reminder, [~jzhuge]. I committed the patch last week, but JIRA went down before I could mark the ticket as resolved. I have committed this to trunk only for the moment. The backport to branch-2 looks like it might be a little tricky, and our next release will be 3.0 anyway. If anyone is interested in backporting to branch-2, please do and update the ticket. Cheers. > TCP_NODELAY not set before SASL handshake in data transfer pipeline > ------------------------------------------------------------------- > > Key: HDFS-9805 > URL: https://issues.apache.org/jira/browse/HDFS-9805 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Reporter: Gary Helmling > Assignee: Gary Helmling > Fix For: 3.0.0-alpha1 > > Attachments: HDFS-9805.002.patch, HDFS-9805.003.patch, > HDFS-9805.004.patch, HDFS-9805.005.patch > > > There are a few places in the DN -> DN block transfer pipeline where > TCP_NODELAY is not set before doing a SASL handshake: > * in {{DataNode.DataTransfer::run()}} > * in {{DataXceiver::replaceBlock()}} > * in {{DataXceiver::writeBlock()}} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
