前面我们已经搭建了hadoop基本平台。由于namenode节点唯一，出现故障，就会瘫痪，恢复时间长。而在生产环境需要做到高可用。
第一种方式：
使用Quorum Journal Manager（QJM）功能配置和管理HA HDFS集群。
第二种方式：
使用NFS作为NameNodes所需的共享存储。
这里讲第一种方式。
修改两配置文件：红色标识在原来基础上变化的地方

a. tar -zxvf zookeeper-3.4.5-cdh5.8.0.tar.gz
b. cp /opt/zookeeper-3.4.5-cdh5.8.0/conf/zoo_sample.cfg /opt/zookeeper-3.4.5-cdh5.8.0/conf/zoo.cfg
c. 编辑zoo.cfg如下：
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/opt/zookeeper-3.4.5-cdh5.8.0/data
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888
d:创建myid文件，文件内容分别为1,2,3分别上传至master,slave1,slave2
e:在三台机器上执行
./zkServer.sh start
f: 在master执行 hdfs zkfc -formatZK
[hadoop@master bin]$ ./hdfs zkfc -formatZK

现在kill master 的namenode进程。
则slave1的namenode应友standby变为active
