             Summary: Make the hdfs replication as 1 when it is single node 
cluster
                 Key: AMBARI-14459
                 URL: https://issues.apache.org/jira/browse/AMBARI-14459
             Project: Ambari
          Issue Type: Improvement

By default the replication is 3 which doesn't work when it is single node 
cluster. I meet this issue when I install hdp in one single node.
