> 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}
