> In ranger admin, when creating a hdfs service, if hdfs cluster is in HA mode,you have
to config a lot of configs in hdfs_dev,such as:
> Namenode URL *=hdfs://hdfscluster
> ===Add New Configurations===
> dfs.nameservices=hdfscluster
> dfs.client.failover.proxy.provider.hdfscluster=org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider
> dfs.ha.namenodes.hdfscluster=nn1,nn2
> dfs.namenode.rpc-address.hdfscluster.nn1=hdfs://10.43.159.240:9000
> dfs.namenode.rpc-address.hdfscluster.nn2=hdfs://10.43.159.245:9000
> ===End of add New Configurations===
> And other big data components such as hbase,hive and so on can support HA without config
> lots of "Add New Configurations",it is easy to config a url. like zk queue configuration
in hbase    ,like jdbc url in hive.  In hdfs service, only need to config "fs.default.name"
:
> Namenode URL *=hdfs://hdfscluster                                                   
      【old】 
> Namenode URL *=hdfs://dap230-183:9000,hdfs://dap229-183:9000        【new】
