Rushabh S Shah resolved HDFS-5773. ---------------------------------- Resolution: Not a Problem > 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: 2.0.0-alpha, 3.0.0, 0.23.10 > Reporter: Daryn Sharp > Assignee: Rushabh S Shah > 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 (v6.2#6252)
