Hi, We have a cluster where we running HDFS in non-rack-aware mode. Now, we want to switch HDFS to run in rack-aware mode. Apart from the config changes (and restarting HDFS), to rackify the existing data, we were thinking of increasing/decreasing replication level a few times to get the data spread. Are there any tools that will enable us to know when we are "done"?
