Jing Zhao updated HDFS-4563:
----------------------------
Attachment: HDFS-4563.002.patch
Update the patch to address Nicholas's comments. As part of the patch, I moved
EnumCounters to diff as the original proposal of HDFS-4574, and to fix the
compilation error, I moved the Content enum out of INode as a separate file.
For cleanSubtreeRecursively(...), I did not pass in Quota.Counts as parameter
considering we need to update the quota usage for each individual
INodeDirectoryWithQuota in the subtree. We may have to do extra operations to
calculate the difference of the passed-in counts before/after processing each
subtree if we use a single counts as parameter.
