Job.jar could only be replicated to 0 nodes, instead of 1(IO Exception)

I am trying to run K-Means using Hadoop.  I first wanted to test it within a
single-node cluster.  And this was the error I got.  What could be the
problem?

$ bin/hadoop jar clustering.jar
com.company.analytics.clustering.mr.core.KMeansDriver
Iteration 0
org.apache.hadoop.ipc.RemoteException: java.io.IOException: File
/WORK/temp/hadoop/workspace/hadoop-user/mapred/system/job_200804291904_0001/job.jar

My data node is up.  The problem went away when I just re-formatted the
folder.  Could have been a problem because of corruption.

Check if your datanode is up or not.
