> After investigating, we noticed that ZKDelegationTokenSecretManager normally
> initializes properties for ZooKeeper clients to connect using SASL/Kerberos.
> If ZKDelegationTokenSecretManager is replaced with a new SecretManager, the
> SASL properties don't get configured and any StateStores that connect to
> ZooKeeper fail with the above error.
> A potential way to fix this is by setting the JaasConfiguration (currently
> done in ZKDelegationTokenSecretManager) as part of the
> StateStoreZooKeeperImpl initialization method.
