Janus Chow created HDFS-16348: --------------------------------- Summary: Mark slownode as badnode to recover pipeline Key: HDFS-16348 URL: https://issues.apache.org/jira/browse/HDFS-16348 Project: Hadoop HDFS Issue Type: Improvement Reporter: Janus Chow Assignee: Janus Chow
In HDFS-16320, the DataNode can retrieve the SLOW status from each NameNode. This ticket is to send this information back to Clients who are writing blocks. If a Clients noticed the pipeline is build on a slownode, he/she can choose to mark the slownode as a badnode to exclude the node or rebuild a pipeline. In order to avoid the false positives, we added a config of "threshold", only clients continuously receives slownode reply from the same node will the node be marked as SLOW. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
