>         Environment: HDP 2.5.3.0

>            Reporter: Greg Senia
>         Attachments: HADOOP-13988.01.patch, HADOOP-13988.02.patch, HADOOP-13988.patch, HADOOP-13988.patch

> After upgrading to HDP 2.5.3.0 noticed that all of the KMSClientProvider issues have not been resolved. We put a test build together and applied HADOOP-13558 and HADOOP-13749 these two fixes did still not solve the issue with requests coming from WebHDFS through to Knox to a TDE zone.
> So we added some debug to our build and determined effectively what is happening here is a double proxy situation which does not seem to work. So we propose the following fix in getActualUgi Method:
> {noformat}
>      }
>      // Use current user by default
>      UserGroupInformation actualUgi = currentUgi;
>      if (currentUgi.getRealUser() != null) {
>        // Use real user for proxy user
>        if (LOG.isDebugEnabled()) {
> 	   LOG.debug("using RealUser for proxyUser);
> 	}
>        actualUgi = currentUgi.getRealUser();
>        if (getDoAsUser() != null) {
>       	  if (LOG.isDebugEnabled()) {
> 		LOG.debug("doAsUser exists");
> 		LOG.debug("currentUGI realUser shortName: {}", currentUgi.getRealUser().getShortUserName());
> 		LOG.debug("processUGI loginUser shortName: {}", UserGroupInformation.getLoginUser().getShortUserName());
>           }
>     	  if (currentUgi.getRealUser().getShortUserName() != UserGroupInformation.getLoginUser().getShortUserName()) {
>     		  if (LOG.isDebugEnabled()) {
> 		  	LOG.debug("currentUGI.realUser does not match UGI.processUser);
> 		  }
> 		  actualUgi = UserGroupInformation.getLoginUser();
> 		  if (LOG.isDebugEnabled()) {
> 	    	  	LOG.debug("LoginUser for Proxy: {}", actualUgi.getLoginUser());
> 		  }
>      	  }
>        }
> 	
>      } else if (!currentUgiContainsKmsDt() &&
>          !currentUgi.hasKerberosCredentials()) {
>        // Use login user for user that does not have either
>        // Kerberos credential or KMS delegation token for KMS operations
