Subject Quickstart: only replicated to 0 nodes
Date Thu, 06 Nov 2008 06:45:32 GMT
So I'm new to Hadoop and I have been trying unsuccessfully to work
through the Quickstart tutorial to get a single node working in
pseudo-distributed mode. I can't seem to put data into HDFS using
release 0.18.2 under Java 1.6.0_04-b12:

$ bin/hadoop fs -put conf input
08/11/05 18:32:23 INFO dfs.DFSClient:
org.apache.hadoop.ipc.RemoteException: java.io.IOException: File
/user/slaurent/input/commons-logging.properties could only be
replicated to 0 nodes, instead of 1

The dfshealth jsp page reports 1 live datanode. The strange thing is
that the node listed as "dkz216" with a url of
not sure where that came from.

No errors in the log files, other than the replication error. However,
I do see one other oddity in the datanode logfile:

2008-11-05 18:32:28,317 INFO org.apache.hadoop.dfs.DataNode:
dnRegistration =
DatanodeRegistration(dkz216.neoplus.adsl.tpnet.pl:50010, storageID=,
infoPort=50075, ipcPort=50020)

Here are my config files:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->




I originally started with localhost everywhere but then switched to to see if that helped. No luck. I can't seem to copy any
files to HDFS.

Any suggestions would be greatly appreciated!
