> The {{getTokenStore}} method will not work for the {{DBTokenStore}} and {{ZKTokenStore}} since they implement {{org.apache.hadoop.hive.thrift.DelegationTokenStore}} instead of  {{org.apache.hadoop.hive.metastore.security.DelegationTokenStore}}
> {code}
> private DelegationTokenStore getTokenStore(Configuration conf) throws IOException {
>     String tokenStoreClassName =
>         MetastoreConf.getVar(conf, MetastoreConf.ConfVars.DELEGATION_TOKEN_STORE_CLS, "");
>     // The second half of this if is to catch cases where users are passing in a HiveConf for
>     // configuration.  It will have set the default value of
>     // "hive.cluster.delegation.token.store .class" to
>     // "org.apache.hadoop.hive.thrift.MemoryTokenStore" as part of its construction.  But this is
>     // the hive-shims version of the memory store.  We want to convert this to our default value.
