Xiaobing Zhou commented on HDFS-10824:
--------------------------------------

Thank you [~cnauroth] and [~arpitagarwal] for comments. I will look into the 
failure.
storageCap is intentionally typed as List<long[]> since startDataNodes is used 
to start new DNs in existing cluster. The list is to retain old cap setting and 
append new caps so that they are both remembered for DNs restart.

> MiniDFSCluster#storageCapacities has no effects on real capacity

> It has been noticed MiniDFSCluster#storageCapacities has no effects on real 
> capacity. It can be reproduced by explicitly setting storageCapacities and 
> then call ClientProtocol#getDatanodeStorageReport(DatanodeReportType.LIVE) to 
> compare results. The following are  storage report for one node with two 
> volumes after I set capacity as 300 * 1024. Apparently, the capacity is not 
> changed.
