when I say
hadoop fs -copyFromLocal small_yeast /user/training/small_yeast

I get

org.apache.hadoop.ipc.RemoteException: java.io.IOException: File
/user/training/small_yeast/yeast_chrXIV00000006.sam.gz could only be
replicated to 0 nodes, instead of 1
        at sun.reflect.GeneratedMethodAccessor841.invoke(Unknown Source)
        at java.lang.reflect.Method.invoke(Method.java:597)
        at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:508)
Anyone seen this and know how to fix it
 I am on a 4 node virtual cloudera cluster
