nkeywal created HDFS-3704: ----------------------------- Summary: In the DFSClient, Add the node to the dead list when the ipc.Client calls fails Key: HDFS-3704 URL: https://issues.apache.org/jira/browse/HDFS-3704 Project: Hadoop HDFS Issue Type: Improvement Affects Versions: 2.0.0-alpha, 1.0.3 Reporter: nkeywal Priority: Minor
The DFSCLient maintains a list of dead node per input steam. When creating this DFSInputStream, it may connect to one of the nodes to check final block size. If this call fail, this datanode should be put in the dead nodes list to save time. If not it will be retried for the block transfer during the read, and we're likely to get a timeout. -- This message is automatically generated by JIRA.
