--------------------------------

             Summary: Refactor: Consistent method signature for QuotaCounts and DirectoryWithQuotaFeature
class
                 Key: HDFS-7775
                 URL: https://issues.apache.org/jira/browse/HDFS-7775
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao
            Priority: Minor


This is based on the code review feedback from [~arpitagarwal] on HDFS-7723. We decide to
put the refactoring/renaming work in a separate JIRA to avoid further increasing the size
of current patch for HDFS-7723. Below is the initial refactoring to-do list.

* QuotaCounts: typeSpaces and typeCounts are used interchangeably. We should probably name
them consistently.

* You renamed DEFAULT_DISKSPACE_QUOTA to DEFAULT_SPACE_QUOTA. DEFAULT_STORAGE_SPACE_QUOTA
would be easier to understand. Comments like @return the namespace and diskspace consumed
can also be edited to use storage space instead of diskspace. 

* Add Javadocs to FsImageFormat.java on why storage type quota for FSImageFormat.java. "We
don't have quota by storage type record in legacy fsimages, which is handled in this FSImageFormat
class (used by legacy_oiv only). The current fsimage processing is done in the protobuf based
class FSImageFormatProtobuf, which is updated with typeCounts by HDFS-7723."
