Hitesh Shah commented on YARN-727:
----------------------------------

Comments:

 - Usage/helper documentation for ApplicationCLI has not been updated for 
--list. 
 - TestYarnCLI.java does not test the new appType argument
 - In ClientRMService#getAllApplications, 
"application.createAndGetApplicationReport" is being called twice in the for 
loop.

Also, the code could be made a bit more optimal:

{code}
    for (RMApp application : this.rmContext.getRMApps().values()) {
      String appType = application.getApplicationType();
      if (!(bypassFilter || applicationType.equals(appType))) {
        continue;
      }
      boolean allowAccess = checkAccess(callerUGI, application.getUser(),
          ApplicationAccessType.VIEW_APP, application.getApplicationId());
      reports.add(application.createAndGetApplicationReport(allowAccess));
    }
{code}
                
> ClientRMProtocol.getAllApplications should accept ApplicationType as a 
> parameter
