Trying file transfer from one cluster to another cluster in HA environment.

1.Added HA clusters multiple nameservices in hdfs-site.xml file

2. Stop and Start hadoop all services

3. Namenode service is down below error message.

org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /home/rajesh/tmp/dfs/name is in an inconsistent state: storage directory does not exist or is not accessible.

4. CHecked cluster service active or standby it failed.

[rajesh@mashdp ~]$ hdfs haadmin -getServiceState nn1 Illegal argument: Unable to determine the nameservice id. [rajesh@mashdp ~]$ hdfs haadmin -getServiceState nn2 Illegal argument: Unable to determine the nameservice id. [rajesh@mashdp ~]$ hdfs haadmin -getServiceState mn1 Illegal argument: Unable to determine the nameservice id. [rajesh@mashdp ~]$ hdfs haadmin -getServiceState mn2 Illegal argument: Unable to determine the nameservice id.

5. hdfs command also down.

It will be helpful if you attach the complete hdfs-site.xml from both the clusters (you can anonymize hostnames and IP addresses).

@Rajesh Dheenan

Your service name is as following:

<property>
<name>dfs.ha.namenodes.raccluster</name>
<value>mn1,mn2</value>
</property>
<property>
<name>dfs.namenode.rpc-address.raccluster.mn1</name>
<value>namnod1:8020</value>
</property>
<property>
<name>dfs.namenode.rpc-address.raccluster.mn2</name>
<value>namnod2:8020</value>
</property>
<property>
<name>dfs.namenode.http-address.raccluster.mn1</name>
<value>namnod1:50070</value>
</property>
<property>
<name>dfs.namenode.http-address.raccluster.mn2</name>
<value>namnod2:50070</value>
</property>

So please try the following commands: (Notice i am using mn1 and mn2 instead of nn1 & nn2)

# hdfs haadmin -getServiceState mn1
# hdfs haadmin -getServiceState mn2
