I use hadoop-2.0.5 version, and I use QJM for HA. I want to there are two Standby NameNodes and one Active NameNode in HDFS cluster,
I think I need to config below content: <property> <name>dfs.ha.namenodes.mycluster</name> <value>nn1,nn2,nn3</value> </property> <property> <name>dfs.namenode.rpc-address.mycluster.nn1</name> <value>10.232.98.77:20020</value> </property> <property> <name>dfs.namenode.rpc-address.mycluster.nn2</name> <value>10.232.98.78:20020</value> </property> <property> <name>dfs.namenode.rpc-address.mycluster.nn3</name> <value>10.232.98.79:20020</value> </property> <property> <name>dfs.client.failover.proxy.provider.mycluster</name> <value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value> </property> Can I do that? Thanks, LiuLei
