11.1.2 hdfs

如果部署新的zk实例选择依赖新的zookeeper（建议部署新的zookeeper）

新实例按照常规部署流程部署，需要修改以下配置

global:

cluster_name (与旧实例不同，推荐easyops-cluster-dev)

znode (共用一个zookeeper时必须与旧实例不同，不同zookeeper不需要修改)

ranger:

ranger_repo_name (与旧实例不同，推荐easyops-cluster-dev)

hdfs-site: (添加以下配置，根据旧实例对应值修改)

dfs.nameservices=easyops-cluster-dev,easyops-cluster （新实例cluster_name，旧实例cluster_name）

dfs.client.failover.proxy.provider.easyops-cluster=org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider

dfs.ha.namenodes.easyops-cluster=nn1,nn2

dfs.namenode.http-address.easyops-cluster.nn1=mammut4-dev.jdlt.163.org:50070

dfs.namenode.http-address.easyops-cluster.nn2=mammut5-dev.jdlt.163.org:50070

dfs.namenode.https-address.easyops-cluster.nn1=mammut4-dev.jdlt.163.org:50470

dfs.namenode.https-address.easyops-cluster.nn2=mammut5-dev.jdlt.163.org:50470

dfs.namenode.rpc-address.easyops-cluster.nn1=mammut4-dev.jdlt.163.org:8020

dfs.namenode.rpc-address.easyops-cluster.nn2=mammut5-dev.jdlt.163.org:8020

dfs.namenode.servicerpc-address.easyops-cluster.nn1=mammut4-dev.jdlt.163.org:8021

dfs.namenode.servicerpc-address.easyops-cluster.nn2=mammut5-dev.jdlt.163.org:8021

dfs.internal.nameservices:easyops-cluster-dev（新实例cluster_name）

为服务增加标签，标识为开发环境服务，

在配置服务步骤，点击高级选项，填写字段名为cluster_env,字段值为test

点击安装完成即可。

旧实例修改以下配置：

hdfs-site: （添加以下配置，根据新实例对应值修改）

dfs.nameservices=easyops-cluster-dev,easyops-cluster （新实例cluster_name，旧实例cluster_name）

dfs.client.failover.proxy.provider.easyops-cluster-dev=org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider

dfs.ha.namenodes.easyops-cluster-dev=nn1,nn2

dfs.namenode.http-address.easyops-cluster-dev.nn1=mammut4-dev.jdlt.163.org:50070

dfs.namenode.http-address.easyops-cluster-dev.nn2=mammut5-dev.jdlt.163.org:50070

dfs.namenode.https-address.easyops-cluster-dev.nn1=mammut4-dev.jdlt.163.org:50470

dfs.namenode.https-address.easyops-cluster-dev.nn2=mammut5-dev.jdlt.163.org:50470

dfs.namenode.rpc-address.easyops-cluster-dev.nn1=mammut4-dev.jdlt.163.org:8020

dfs.namenode.rpc-address.easyops-cluster-dev.nn2=mammut5-dev.jdlt.163.org:8020

dfs.namenode.servicerpc-address.easyops-cluster-dev.nn1=mammut4-dev.jdlt.163.org:8021

dfs.namenode.servicerpc-address.easyops-cluster-dev.nn2=mammut5-dev.jdlt.163.org:8021

dfs.internal.nameservices:easyops-cluster （旧实例cluster_name）

旧实例重启并同步配置
