Summary: Stack trace should not be printed out when running hadoop
key commands
Key: HADOOP-15596
URL: https://issues.apache.org/jira/browse/HADOOP-15596
Project: Hadoop Common
Issue Type: Improvement
Components: common
Affects Versions: 3.1.0

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 commandÂ
{code}
-bash-4.1$ hadoop key list
Cannot list keys for KeyProvider:
