             Summary: Improve error handling in fast hdfs tool
                 Key: AMBARI-25230
                 URL: https://issues.apache.org/jira/browse/AMBARI-25230
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.6.2, 2.7.3
            Reporter: Balázs Bence Sári
            Assignee: Balázs Bence Sári
             Fix For: 2.7.4


There are cases when the fast hdfs tool swallows the original exception an 
exits with an NPE hiding the original issue. The original exception is logged 
to the standard out but that may not be captured by calling tools.

Fixing exception handling would not affect normal tool execution but help 
finding the issue in error cases.
