Review Comment:
If everything works as expected yes, but no there is not granted some one
will not call this method again ...
you right this should be in SecretManager not in an other class
> SecretManager configuration at runtime

> Project: Hadoop Common
> Issue Type: Improvement
> Components: hadoop-common
> Affects Versions: 3.5.0
> Reporter: Bence Kosztolnik
> Assignee: Bence Kosztolnik
> Priority: Major
> Labels: pull-request-available
>
> In case of TEZ *DAGAppMaster* the Hadoop *SecretManager* code can not read
> yarn config xml file, therefore the SELECTED_ALGORITHM and SELECTED_LENGTH
> variables in SecretManager can not be set at runtime.
> This can results with the following exception in FIPS environment:
> {code:java}
> java.security.InvalidParameterException: Key size for HMAC must be at least
> 112 bits in approved mode: SHA-1/HMAC
