title: Increase size of hdfs in hdinsight cluster
body: <p>Hi I'm playing around with hdinsight. Just started with creating a cluster in hdinsight but having trouble to understand how the HDFS is created. Is it using the local disk of datanodes or the azure storage(as i selected it while creating the cluster) I want to increase the size of HDFS in my cluster, how can i do it? Should i attach a managed disk to every datanode?
  Thanks in advance.</p>
