Description

This was found when I'm documenting the quota by storage type feature. The current usage string to set/clear quota by storage type which put the -storageType prameter after dirnames is incorrect.
"hdfs dfsadmin -setSpaceQuota/clrSpaceQuota <quota> <dirname>...<dirname> -storageType <storagetype>".

The correct one should be:
"hdfs dfsadmin -setSpaceQuota/clrSpaceQuota <quota> [-storageType <storagetype>] <dirname>...<dirname>"

I will post the fix shortly.
