>      When setReplication, the FSDirectory#updateCount need calculate the related storageTypes
quota,but will check the file consume the ds quota is positive.
>      Actually,it's may set replication after create file,like  JobSplitWriter#createSplitFiles.
>     It's also can reproduce on command shell:
>     1.  hdfs storagepolicies -setStoragePolicy -path /tmp -policy HOT
>     2.  hdfs dfs -touchz /tmp/test
>     3.  hdfs dfs -setrep 5 /tmp/test
