Daryn Sharp created HDFS-5773: --------------------------------- Summary: NN may reject formerly dead DNs Key: HDFS-5773 URL: https://issues.apache.org/jira/browse/HDFS-5773 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 0.23.10, 2.0.0-alpha, 3.0.0 Reporter: Daryn Sharp Priority: Critical
If the heartbeat monitor declares a node dead, it may never allow a DN to rejoin. The NN will generate messages like "Got blockReceivedDeleted message from unregistered or dead node". There appears to be a bug where the the isAlive flag is not set to true when a formerly known DN attempts to rejoin. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
