We are using dictcp to copy data from CDH4 to CDH5. When we run the command on CDH5 destination namenode, we get the following exception. Please let me know if you have already encountered the problem and know the solution. Thanks.

Seems like this is because of protocol mismatch between two clusters.
As Hadoop version used in the source and destinations are different, you cannot use distcp by using hdfs://Cluster2-Namenode1:Port/ in source or destination, you have to use webhdfs:// instead of simple hdfs as follows.
hadoop distcp /source-directory webhdfs://Cluster2-Namenode1:50070/dir/
Please note 50070 is the default namenode Web UI, If you have configured different port for HDFS namenode WebUI, modify 50070 to your modified port.

I have installed hive(2.1.1) on Hadoop(2.7.3) in aws ec2 Ubuntu 14.04 instance.
Earlier I was able start hive by just typing commands start-all.sh and hive now when I try to do it again, I am getting the following error:

How can I solve it?
(I also tried hdfs dfsadmin -safemode leave)
My disk space was low and my hdfs was full so I cleaned hdfs and was able to start hive smoothly.
I used the following commands:
hdfs dfsadmin -report
hdfs dfsadmin -safemode leave
hdfs dfs -rm -R directory/name/which/contains/waste/files
Special Thanks for #philantrovert :)
I have configured Hadoop 2.7.2 on Windows, I can see name node, data node, resource manager and node manager are running properly, problem occures when I try to run one of the map reduce program provided as example.

I can see all the files are present at the desired locations.

if you are running everything on the same machine, you can just refer to it with a file: URL, like file://c:/hdp/LICENSE.txt, [maybe it's file:/c:/hdp/LICENSE.txt; I forget the naming logic]
LICENSE.txt (first argument for wordcount) should be located in HDFS, not on your local machine.
I would like to transfer data between 2 hadoop clusters located on different servers.
Source:
hadoop version
Hadoop 2.0.0-cdh4.3.1
Destination:
hadoop version
Hadoop 2.0.0-cdh4.3.1
I have a directory in source as:
hadoop fs -ls /bid_data/foo
I have a directory in destination as:
hadoop fs -ls /bid_data
I want to copy the /bid_data/foo directory and its content inside /bid_data in another cluster
Thank you,
Rio
=
updated:
Below is the error message I get when I use below command: Is it a firewall issue? The destination cluster is not open to the world which means I need VPN to access the destination cluster outside the local area network.

Hadoop provides an option to transfer data from one cluster to another. Its Distcp
The command for the same is
hadoop distcp hdfs://nn1:8020/bid_data/foo hdfs://nn2:8020/bid_data

please any one help me
Check that every proccess is up by running "jps". The jobtracker must be up and appear in the list of your localhost computer
Namenode
Jobtracker
Tasktracker
Datanode
SecondaryNamenode
If it is not up it might be that another proccess is using the same port (54311) or simply a firewall problem
I hope it helps

I am also trying to run wordcound program. While copying data into HDFS using command
$bin/hadoop dfs -copyFromLocal /home/hadoop1/Documents/wordcount/ /home/hadoop1/hdfs/data
I get following error

Help in this regard is appreciated..
I managed to solve this issue...
Step I) There was firewall active on master and slaves node machines..
I disabled it by following command "systemctl disable iptables.service"
Step II) I wrongly assigned "hdfs://localhost:9100" to "fs.default.name" in slave's core-sites.xml configuration file. I changed it to "hdfs://master:9100"
Now my Hadoop Cluster is Up..
Thank You Chris for your kind help...
My reason for this error was not enough space on disk (~200MB was not enough).
I delete jobtracker.info on HDFS, then it works.
Hadoop seems to remake it
One more reason for this error (which I encountered) is a messed up /etc/hosts file causing namenode to listen only on the loopback interface.
This caused datanodes not to connect to namenode and replication level was not reached as a side effect. See namenode rejecting connections bug for more detail.
