    Description

      When upgrading hdfs cluster from 2.10.2 to 3.3.6, the results returned from dfs count command is inconsistent.

      Reproduce

      Start up 2.10.2 hdfs cluster (1 NN, 2 DN, 1 SNN), execute the following commands

      dfs -mkdir /GscWZRxS
      dfs -put -f  -d /tmp/hpLjvJVW/cl /GscWZRxS/
      dfs -put -f  -d /tmp/hpLjvJVW/Zjpk /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR
      dfsadmin -clrQuota /GscWZRxS/cl
      dfsadmin -refreshSuperUserGroupsConfiguration
      dfs -mkdir /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR/Zjpk/Cf/mGpVA
      dfsadmin -refreshCallQueue
      dfsadmin -clrQuota /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd
      dfsadmin -setSpaceQuota 2 -storageType DISK /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR/Zjpk/Cf
      dfsadmin -refreshNodes
      dfsadmin -setSpaceQuota 2 -storageType DISK /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd
      dfsadmin -clrSpaceQuota -storageType ARCHIVE /GscWZRxS/cl
      dfsadmin -restoreFailedStorage true

      before upgrade, check the quota results

      bin/hdfs dfs -count -q -h -u /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR/Zjpk/Cf 
      none             inf            none             inf /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR/Zjpk/Cf 

      Then prepare the upgrade. Enter safemode, create image, shutdown the cluster and start up the new cluster

      bin/hdfs dfs -count -q -h -u /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR/Zjpk/Cf 
      8.0 E           8.0 E            none             inf /GscWZRxS/cl/lBsmFBlyBd/pozIeNFjzd/PsLbgpR/Zjpk/Cf 

      The values of the first two columns are inconsistent with the quota I set before.

      I have attached the file used by the command. I am digging out the root cause, I'll try to submit a patch once I can fix it. Any help is appreciated!
