             Summary: Change CredentialShell to use CommandShell base class
                 Key: HADOOP-13112
                 URL: https://issues.apache.org/jira/browse/HADOOP-13112
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Matthew Paduano
            Assignee: Matthew Paduano
            Priority: Minor


org.apache.hadoop.tools.CommandShell is a base class created for use by 
DtUtilShell.  It was inspired by CredentialShell and much of it was taken 
verbatim.  It should be a simple change to get CredentialShell to use the base 
class and simplify its code without changing its functionality.
