Ran ant test locally (both with and without the patch). Got the same output:

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 0.20.2, 0.22.0
> Reporter: Kang Xiao
> Assignee: John George
> Labels: hdfs, quota
> Fix For: 0.22.0

> HDFS Quota counts will be missed between a clear quota operation and a set
> quota.
> When setting quota for a dir, the INodeDirectory will be replaced by
> INodeDirectoryWithQuota and dir.isQuotaSet() becomes true. When
> INodeDirectoryWithQuota is newly created, quota counting will be performed.
> However, when clearing quota, the quota conf is set to -1 and
> dir.isQuotaSet() becomes false while INodeDirectoryWithQuota will NOT be
> replaced back to INodeDirectory.
> FSDirectory.updateCount just update the quota count for inodes that
> isQuotaSet() is true. So after clear quota for a dir, its quota counts will
> not be updated and it's reasonable. But when re seting quota for this dir,
> quota counting will not be performed and some counts will be missed.
