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.
