Colin Patrick McCabe created HDFS-4911: ------------------------------------------
Summary: Reduce PeerCache timeout to be commensurate with dfs.datanode.socket.reuse.keepalive Key: HDFS-4911 URL: https://issues.apache.org/jira/browse/HDFS-4911 Project: Hadoop HDFS Issue Type: Improvement Reporter: Colin Patrick McCabe Priority: Minor The default timeout for the client's PeerCache is much longer than the DataNode would possibly keep the socket open. Specifically, {{dfs.client.socketcache.expiryMsec}} defaults to 2 * 60 * 1000 (2 minutes), whereas {{dfs.datanode.socket.reuse.keepalive}} defaults to 1000 (1 second). We should make these more similar to minimize situations where the client tries to use sockets which have gone stale. -- This message is automatically generated by JIRA.
