Subject [jira] [Created] (HDFS-7600) Refine hdfs admin classes to reuse common code
Date Mon, 12 Jan 2015 01:51:34 GMT
Yi Liu created HDFS-7600:

             Summary: Refine hdfs admin classes to reuse common code
                 Key: HDFS-7600
                 URL: https://issues.apache.org/jira/browse/HDFS-7600
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Yi Liu
            Assignee: Jing Zhao

As the review comment in HDFS-7323. 
In {{StoragePolicyAdmin}} and other class under {{org.apache.hadoop.hdfs.tools}}, such as
{{CacheAdmin}}, {{CryptoAdmin}}. There are too many common methods ({{getDFS}}, {{prettifyException}},
{{getOptionDescriptionListing}} ...) and also inner class ({{HelpCommand}}), they are the
same, it would be great if we can refine and shift them into a common place.
This makes the code clean and can be re-used if we add new hdfs admin class in future.
