I am trying to setup a CDH4 multi node cluster.
Datanode is down and I get the following FATAL error:
org.apache.hadoop.hdfs.server.datanode.DataNode: Exception in secureMain
java.io.IOException: Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
Does anyone know how to resolve this issue?
Thanks!
Can you please update your configuration files and logs.

Below is the error after cluster kerberized.
Exception in thread "main" java.io.IOException: Login failure for jn/keystone.mwbsys.com#EXAMPLE.COM from keytab /etc/security/keytabs/jn.service.keytab: javax.security.auth.login.LoginException: Unable to obtain password from user
added keystone.mwbsys.com in /etc/hosts file
and then restarted the journal nodes its fixed the issue. I know this is not the permenent solution but it worked.
I have installed/configured Hadoop on windows hadoop-2.6.0
I couldn't successfully start "sbin\start-dfs" run command.
I am getting below error

There was a similar question for running YARN. And it was told that including hadoop-2.6.0/sbin and hadoop-2.6.0/bin in path would resolve the problem. But still i am facing the error.
Can anyone help me in fixing this?
Please make sure you have proper access permission to namenode directory. Also, format the namenode and start the hdfs services.
I have configure hbase on my local machine, below are my jsp task
$ jps
17389 HQuorumPeer
16554 TaskTracker
17894 Jps
16362 JobTracker
15786 NameNode
16078 DataNode
16267 SecondaryNameNode
But when I hit
$ hbase shell
It gives me following error
NativeException: java.lang.ExceptionInInitializerError:
java.lang.reflect.InvocationTargetException
initialize at /home/rahul/hbase-1.2.4/lib/ruby/hbase/hbase.rb:42

Can any one help me to solve this error.I have wasted several hours to solve this error. Help is really appreciated.
Unfortunately this error is very generic and can occur for a number of reasons. I recently experienced this using the hbase command on version HBase 1.2.0-cdh5.16.1 when the wrong URI was configured in core-site.xml and hbase-site.xml (fs.defaultFS and hbase.rootdir respectively). The only way I diagnosed this was to try connecting programmatically via the Java API (e.g. by following https://www.baeldung.com/hbase), which gave me the full stack trace of the exception that caused the NativeException.
I am trying to install Hadoop 2.7 in Ubuntu 14.04 in VMWare. But datanode always failed to start when I do hadoop datanode, I get this error:
This issue is due to Datanode clusterID is not same as Namenode Cluster ID, both should be same and then only the datanode will communicate to Namenode.
Try to stop services and start the namenode after formatting it.
I tried installing hadoop in two nodes. Both the nodes are up and running. The namenode runs on Ubuntu 10.10 and Datanode on Fedora 13. While copying the file from local file system to hdfs I encountered the following errors.
The terminal showed:
12/04/12 02:19:15 INFO hdfs.DFSClient: Exception in createBlockOutputStream java.io.OException: Bad connect ack with firstBadLink as 10.211.87.162:9200
12/04/12 02:19:15 INFO hdfs.DFSClient: Abandoning block blk_-1069539184735421145_1014
The log file in namenode showed:

Datanodes available are indicated as 2. I've disabled the firewall and selinux.
The following changes have also been made in the hdfs-site.xml
dfs.socket.timeout -> 360000
dfs.datanode.socket.write.timeout -> 3600000
dfs.datanode.max.xcievers -> 1048576
Both the nodes run sun-java6-jdk, The datanode contains Openjdk but the path settings have been made for sun java.
Yet the same error persists.
What might be the solution.
That's because your firewall is on.
try
sudo /etc/init.d/iptables stop
If you are on Ubuntu, do
sudo ufw disable
this should solve the issue.
The exception log mentioned tha the failure reason is No route to host.
Try ping 10.6.2.26 to test your network connection.
