Adding the target versions. > IBR leak causes standby NN to be stuck in safe mode > --------------------------------------------------- > > Key: HDFS-15421 > URL: https://issues.apache.org/jira/browse/HDFS-15421 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Reporter: Kihwal Lee > Priority: Blocker > Labels: release-blocker > > After HDFS-14941, update of the global gen stamp is delayed in certain > situations. This makes the last set of incremental block reports from append > "from future", which causes it to be simply re-queued to the pending DN > message queue, rather than processed to complete the block. The last set of > IBRs will leak and never cleaned until it transitions to active. The size of > {{pendingDNMessages}} constantly grows until then. > If a leak happens while in a startup safe mode, the namenode will never be > able to come out of safe mode on its own. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
