HDFS Error while copying the file : Could only be replicated to 0 nodes, instead of 1

While copying file from Local system to HDFS i am getting the below error,I am using Single Node

13/08/04 10:50:02 WARN hdfs.DFSClient: DataStreamer Exception: java.io.IOException: File /user/vishu/input could only be replicated to 0 nodes, instead of 1

I deleted the dfs/Name and dfs/data directories and formated the Namenode still No use. and I have enough space to replicate the Data.

Could anyone help resolving this issue?

Regards, Vishwa

If your Client writing the file is outside the cluster, make sure the client has access to the Datanode.

Look at this http://www.hadoopinrealworld.com/could-only-be-replicated-to-0-nodes/

Check whether all daemons are started or not. make sure that your input file is correct.

Use the following command to copy the file from local to hdfs:

bin/hadoop fs -mkdir abc

bin/hadoop fs -copyFromLocal inputfile abc

Some times the data node may be starting up slowly and this may cause the above issue.. keep some wait time after the start of dfs and mapred demons.

bin/hadoop namenode -format

bin/start-dfs.sh

wait for some 5 min(data node will be up in the time)

bin/start-mapred.sh
