You cannot put all of the required properties > in core-site.xml and hdfs-site.xml for the client to resolve the location of > both active namenodes. If you do, then the datanodes from cluster A may join > cluster B. I can not find a configuration option that tells the datanodes to > federate blocks for only one of the clusters in the configuration. > [1] > http://mail-archives.apache.org/mod_mbox/hadoop-user/201404.mbox/%3CBAY172-W2133964E0C283968C161DD1520%40phx.gbl%3E -- This message was sent by Atlassian JIRA (v6.2#6252)
