Tanping Wang updated HDFS-2086: ------------------------------- Attachment: HDFS-2086.4.patch > If the include hosts list contains host name, after restarting namenode, > datanodes registrant is denied > -------------------------------------------------------------------------------------------------------- > > Key: HDFS-2086 > URL: https://issues.apache.org/jira/browse/HDFS-2086 > Project: Hadoop HDFS > Issue Type: Bug > Components: name-node > Affects Versions: 0.23.0 > Reporter: Tanping Wang > Assignee: Tanping Wang > Fix For: 0.23.0 > > Attachments: HDFS-2086.2.patch, HDFS-2086.3.patch, HDFS-2086.4.patch, > HDFS-2086.patch > > > As the title describes the problem: if the include host list contains host > name, after restarting namenodes, the datanodes registrant is denied by > namenodes. This is because after namenode is restarted, the still alive data > node will try to register itself with the namenode and it identifies itself > with its *IP address*. However, namenode only allows all the hosts in its > hosts list to registrant and all of them are hostnames. So namenode would > deny the datanode registration. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
