Resolving ... > Datanode is marked dead, but datanode process is alive and verifying blocks > --------------------------------------------------------------------------- > > Key: HDFS-1766 > URL: https://issues.apache.org/jira/browse/HDFS-1766 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode > Affects Versions: 0.23.0 > Reporter: Hairong Kuang > Assignee: Hairong Kuang > Attachments: killDN.patch > > > We have a datanode marked dead in the namenode, and it is not taking any > traffic. But it is verifying blocks continuously, so the DataNode process is > definitely not dead. Jstack shows that the main thread and the offerService > thread are gone but the JVM stuck at waiting for other threads to die. It > seems to me that the offerService thread has died abnormally, for example, by > a runtime exception and it did not shut down other threads before exiting. -- This message was sent by Atlassian JIRA (v6.2#6252)
