DFSClient should cache whether addrs are non-local when short-circuiting is enabled -----------------------------------------------------------------------------------
Key: HDFS-2653 URL: https://issues.apache.org/jira/browse/HDFS-2653 Project: Hadoop HDFS Issue Type: Improvement Components: data-node Affects Versions: 0.23.1, 1.0.0 Reporter: Eli Collins Assignee: Eli Collins Something Todd mentioned to me off-line.. currently DFSClient doesn't cache the fact that non-local reads are non-local, so if short-circuiting is enabled every time we create a block reader we'll go through the isLocalAddress code path. We should cache the fact that an addr is non-local as well. -- This message is automatically generated by JIRA.
