-----------------------------------
Summary: Exception handling improvement in RangerMasterKey
Key: RANGER-5337
URL: https://issues.apache.org/jira/browse/RANGER-5337
Project: Ranger
Issue Type: New Feature
Components: kms
Reporter: Vikas Kumar
Assignee: Vikas Kumar
In RangerKeyStoreProvider class, if MasterKey creation fails due to any runtime
error, it only logs the exception message, not the stack trace.
Logging proper stack trace will help in identifying the root cause.
Example:
Tried to create MK with wrong salt size and got following in the log:
{code:java}
2025-09-23 10:16:35,822 ERROR
org.apache.hadoop.crypto.key.RangerKeyStoreProvider: [main]: createProvider()
error
java.lang.RuntimeException: Error while generating Ranger Master key, Error -
null
at
org.apache.hadoop.crypto.key.RangerKeyStoreProvider.generateAndGetMasterKey(RangerKeyStoreProvider.java:542)
~[ranger-kms-*.jar:?]
{code}
Root Cause:
{code:java}
throw new RuntimeException("Error while getting Ranger Master key, Error - " +
e.getMessage());{code}
Instead it should be :
{code:java}
throw new RuntimeException("Error while getting Ranger Master key.", e);{code}
