Todd Lipcon created HDFS-3342: --------------------------------- Summary: SocketTimeoutException in BlockSender.sendChunks could have a better error message Key: HDFS-3342 URL: https://issues.apache.org/jira/browse/HDFS-3342 Project: Hadoop HDFS Issue Type: Improvement Components: data-node Affects Versions: 2.0.0 Reporter: Todd Lipcon Priority: Minor
Currently, if a client connects to a DN and begins to read a block, but then stops calling read() for a long period of time, the DN will log a SocketTimeoutException "480000 millis timeout while waiting for channel to be ready for write." This is because there is no "keepalive" functionality of any kind. At a minimum, we should improve this error message to be an INFO level log which just says that the client likely stopped reading, so disconnecting it. -- This message is automatically generated by JIRA.
