Do you face problem of over uses of HDFS for datanode, frequently it becomes 100% and hence result in a imbalance cluster, thinking of how to solve this problem, for this what we can do is put a parameter called "dfs.datanode.du.reserved" so this will reserve the non HDFS uses disk space and hence leaving the some space remaining for non HDFS uses and solving disk overuses of HDFS .
All the question that scared me now i am trying to scare them .. so that they cant scare others :)
