Hi, ALL;
I have two hadoop cluster named as cluster_1 and cluster_2 with different zookeepers. Now I want to Distcp hdfs files from cluster_1 to cluster_2.
following as cluster_1's and cluster_2's information.
### cluster_1
1, active namenode: g001.server.edu.tk standby namenode: g002.server.edu.tk
2, zookeeper hosts: g003.server.edu.tk g004.server.edu.tk g005.server.edu.tk
### cluster_2
1, active namenode: d001.server.edu.tk standby namenode: d002.server.edu.tk
2, zookeeper hosts: d003.server.edu.tk d004.server.edu.tk d005.server.edu.tk<br>
1, In order to distcp data from cluster_1 to cluster_2, I copied whole hadoop configuration files from $HADOOP_HOME/etc/hadoop to /configurations/hadoop in cluster_1 and added following properties in hdfs-site.xml in g001.server.org.tk: <property>
<name>dfs.nameservices</name>
<value>cluster_1,cluster_2</value>
</property>
<property>
<name>dfs.client.failover.proxy.provider.cluster_2</name>
<value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value>
</property>
<property>
<name>dfs.ha.namenodes.cluster_2</name>
<value>d001.server.edu.tk,d002.server.edu.tk</value> </property>
<property>
<name>dfs.namenode.rpc-address.cluster_2.d001.server.edu.tk</name>
<value>d001.server.edu.tk:8020</value>
</property>
<property>
<name>dfs.namenode.servicerpc-address.cluster_2.d001.server.edu.tk</name>
<value>d001.server.edu.tk:54321</value>
</property>
<property>
<name>dfs.namenode.http-address.cluster_2.d001.server.edu.tk</name>
<value>d001.server.edu.tk:50070</value>
</property>
<property>
<name>dfs.namenode.https-address.cluster_2.d001.server.edu.tk</name>
<value>d001.server.edu.tk:50470</value>
</property>
<property>

<property>

</property>
<property>

<property>
<name>dfs.namenode.https-address.cluster_1.g002.server.edu.tk</name>
<value>g002.server.edu.tk:50470</value>
</property>
2, Then I ran the Distcp command in g001.server.org.tk: hdfs --config /configurations/hadoop distcp -update -p hdfs://cluster_1:8020/tmp/ hdfs:/cluster_2:8020/tmp/ 3, But got errors like: 18/10/08 07:55:00 ERROR tools.Distcp: Exception encountered
