hdfs-site.xml namespace1 && namespace2 !!!
在 hdfs-site.xml 文件中的 dfs.namenode.shared.edits.dir 配置项：
当配置文件所在节点处于namespace1集群时，此处值末尾部分为namespace1，当处于namespace2集群时，则为namespace2.
启动过程
零，格式化zkfc
在namespace1 nn1（VECS00001） && namespace2(VECS00004) nn1 do:
sudo su - hdfs
hdfs zkfc -formatZK
一，格式化namenode
在namespace1 nn1（VECS00001） && namespace2(VECS00004) nn1 do: （必须指定 clusterid）
hdfs namenode -format -clusterid XXXXXXX
二，启动格式化过后的nn
在namespace1 nn1（VECS00001） && namespace2(VECS00004) nn1 do:
sudo su - hdfs
hadoop-daemons.sh start namenode
三，standbu nn 同步active 元数据
在namespace1 nn2（VECS00002） && namespace2(VECS00005) nn2 do:
sudo su - hdfs
hdfs namenode -bootstrapStandby
hadoop-daemons.sh start namenode
同步完后 并启动
四，启动zkfc
在namespace1 nn1 nn2 && namespace2 nn1 nn2 do:
sudo su - hdfs
hadoop-daemons.shstart zkfc
启动集群所有datanode
hadoop-daemon.sh start datanode
五，启动yarn 集群
start resourcemanager
start nodemanager
start webproxy
start historyserver
