Rebalance HDFS in the host web view, it will not show the Rebalance HDFS dialog to fill the disk capacity value, so the default threshold should be the default value, but the namenode.py not given a default value, so rebalance hdfs wil fail. It would be difficult to change from fore-end, moreover, the change may not fit into fore-end's design ,and I sense the bug is a serious issue, so I think it is better to give it the default value in the namenode.py . - wang ----------------------------------------------------------- This is an automatically generated e-mail.
