             Summary: Update quota usage when deleting a file/dir that is not included in the latest snapshot
                 Key: HDFS-4636
                 URL: https://issues.apache.org/jira/browse/HDFS-4636
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


This jira aims to fix two bugs in deleting files with snapshot:

1. We should update the quota usage when the file/dir to be deleted is not included in the latest snapshot (i.e., the to-be-deleted file/dir is recorded in the created list of the latest snapshot). In particular, in FSDirectory#removeLastINode, instead of checking if the latest snapshot is null to decide whether we should update the quota usage, we should use INode#isInLatestSnapshot(Snapshot) as the check condition.

2. Similarly, in FSDirectory#unprotectedDelete(...), we should update quota usage after calling INode#cleanSubtree, considering during cleanSubtree() we may delete files that were created after taking the latest snapshot.
