> Normally the HDFS cluster is HA enabled. It could take a long time when
> coping huge data by distp. If the source cluster changes active namenode, the
> distp will run failed. This patch supports the DistCp can read source cluster
> files in HA access mode. A source cluster configuration file needs to be
> specified (via the -sourceClusterConf option).
> The following is an example of the contents of a source cluster
> configuration
> file:
> {code:xml}
> <configuration>
> <property>
> <name>fs.defaultFS</name>
> <value>hdfs://mycluster</value>
> </property>
> <property>
> <name>dfs.nameservices</name>
> <value>mycluster</value>
> </property>
> <property>
> <name>dfs.ha.namenodes.mycluster</name>
> <value>nn1,nn2</value>
> </property>
> <property>
> <name>dfs.namenode.rpc-address.mycluster.nn1</name>
> <value>host1:9000</value>
