Gary Helmling reassigned HDFS-9700: ----------------------------------- Assignee: Gary Helmling > DFSClient and DFSOutputStream do not respect TCP_NODELAY config in two spots > ---------------------------------------------------------------------------- > > Key: HDFS-9700 > URL: https://issues.apache.org/jira/browse/HDFS-9700 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client > Affects Versions: 2.7.1, 2.6.3 > Reporter: Gary Helmling > Assignee: Gary Helmling > Attachments: HDFS-9700-v1.patch, HDFS-9700_branch-2.7.patch > > > In {{DFSClient.connectToDN()}} and > {{DFSOutputStream.createSocketForPipeline()}}, we never call > {{setTcpNoDelay()}} on the constructed socket before sending. In both cases, > we should respect the value of ipc.client.tcpnodelay in the configuration. > While this applies whether security is enabled or not, it seems to have a > bigger impact on latency when security is enabled. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
