> 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.
> if (StringUtils.isBlank(tokenStoreClassName) ||

> "org.apache.hadoop.hive.thrift.MemoryTokenStore".equals(tokenStoreClassName))

> return new MemoryTokenStore();
