[jira] [Created] (HDFS-13530) NameNode: Fix NullPointerException when getQuotaUsageInt() invoked

liuhongtong created HDFS-13530:
----------------------------------

             Summary: NameNode: Fix NullPointerException when getQuotaUsageInt() invoked
                 Key: HDFS-13530
                 URL: https://issues.apache.org/jira/browse/HDFS-13530
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: federation, namenode
            Reporter: liuhongtong


If the directory is nonexistent, getQuotaUsage rpc call will run into 

NullPointerException throwed by

FSDirStatAndListingOp.getQuotaUsageInt() .

I think FSDirStatAndListingOp.getQuotaUsageInt() should throw FileNotFoundException when the directory is nonexistent.
