Chris Nauroth created HDFS-11034: ------------------------------------ Summary: Provide a command line tool to clear decommissioned DataNode information from the NameNode without restarting. Key: HDFS-11034 URL: https://issues.apache.org/jira/browse/HDFS-11034 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Reporter: Chris Nauroth
Information about decommissioned DataNodes remains tracked in the NameNode for the entire NameNode process lifetime. Currently, the only way to clear this information is to restart the NameNode. This issue proposes to add a way to clear this information online, without requiring a process restart. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
