hadoop 2.2.0 cluster setup error : could only be replicated to 0
nodes instead of minReplication (=1)
Hi,
I setup a cluster with
machine1 : namenode and datanode
machine 2 : data node
A simple hdfs copy is not working. Can someone help with this issue ?
Several folks have posted this error on the web, But I have seen a good
reason or solution.
command:
bin/hadoop fs -copyFromLocal ~/hello /manoj/
Error:
copyFromLocal: File /manoj/hello._COPYING_ could only be replicated to 0
nodes instead of minReplication (=1). There are 2 datanode(s) running and
no node(s) are excluded in this operation.
14/02/24 12:56:38 ERROR hdfs.DFSClient: Failed to close file
/manoj/hello._COPYING_
org.apache.hadoop.ipc.RemoteException(java.io.IOException): File
/manoj/hello._COPYING_ could only be replicated to 0 nodes instead of
minReplication (=1). There are 2 datanode(s) running and no node(s) are
excluded in this operation.

</property>

hdfs-site.xml

<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.permissions</name>
<value>false</value>
</property>
</configuration>
slaves:
localhost
n-prd-bst-beacon02.advertising.aol.com
Namenode and Datanode (on both machines) are up & running without errors

Re: hadoop 2.2.0 cluster setup error : could only be replicated to 0
nodes instead of minReplication (=1)
Posted by Azuryy Yu <az...@gmail.com>.
Generally, this is caused by insufficient space.
please check the total capacity of your cluster and used, remaining ratio,
and check dfs.datanode.du.reserved in the hdfs-site.xml
if this value is larger than your remained capacity, then you got this
Exception.

Re: hadoop 2.2.0 cluster setup error : could only be replicated to 0
nodes instead of minReplication (=1)
Posted by Manoj Khangaonkar <kh...@gmail.com>.
Hi
Can one of the implementors comment on what conditions trigger this error ?
All the data nodes show up as commissioned. No errors during startup
If I google for this error, there are several posts reporting the issue :
but most of the answers have weak solutions like reformating and restarting
none of which help.
My guess is that this is a networking /port access issue. If anyone can
shed light on what conditions cause this error , it would be much
appreciated.
regards
