Hairong Kuang commented on HADOOP-4281:
---------------------------------------
The patch looks good. I have two minor comments:
1. In DFSAdmin.java, it would be nice to switch the following two statements
+ long presentCapacity = ds.getDfsUsed() + ds.getRemaining();
+ long used = ds.getDfsUsed();
to be
long used = ds.getDfsUsed();
long presentCapacity = used + ds.getRemaining();
2. In DatanodeInfo.toString, it would be nice to use dfs.getDfsUsedPercent()
to calculate the %Used.
I think Suresh meant to mark this issue as a block to 0.19. I will mark it for
him.
