Subject [jira] [Updated] (HADOOP-15596) Stack trace should not be printed out when running hadoop key commands
Date Tue, 10 Jul 2018 14:52:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15596?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kitti Nanasi updated HADOOP-15596:
----------------------------------
    Description: 
Stack trace is printed out if any exception occurs while executing hadoop key commands. The
whole stack trace should not be printed out.

For example when the kms is down, we get this error message for the hadoop key list command:
{code:java}
 -bash-4.1$ hadoop key list
 Cannot list keys for KeyProvider: KMSClientProvider[http://example.com:16000/kms/v1/]: Connection
