Hi When we tried to run the hadoop flows we got the following exception for all the tasks and it is failed.error is little bit confusing.I have two data nodes,but both are healthy and nodes are Up and running. com.ericsson.cim.base.core.exception.CimProcessingException: Could not sink. Got an IOException with message: org.apache.hadoop.ipc.RemoteException: java.io.IOException: File /data/processing/events/usage/Processed_at_20111215100837/_temporary/_attempt_201112150454_0036_m_000000_0/ServiceUsageChargedAccBalCS4_20111001-m-00000 could only be replicated to 0 nodes, instead of 1 at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getAdditionalBlock(FSNamesystem.java:1282) at org.apache.hadoop.hdfs.server.namenode.NameNode.addBlock(NameNode.java:469) at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:512) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:968) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:964) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:962)
