I am trying to put one small file in newly created cluster and it gives me error

java.io.IOException: Unable to create new block. at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.nextBlockOutputStream(DFSOutputStream.java:1284)

@Swapnil Prabhu is your cluster up? Please check Ambari whether hdfs service is up. The other issue you may have is native library, search HCC for instructions to fix "unable to load native-hadoop library"

@Swapnil Prabhu please run HDFS service check and report results.
