luoyuxia commented on FLINK-27191:
----------------------------------
About the confict with TM's, the idea is when every call involving with
hdfs/hive metastore, switch the user like using the following code:
{code:java}
final Configuration conf = new Configuration();
UserGroupInformation ugi =
UserGroupInformation.loginUserFromKeytabAndReturnUGI(userCode, keytabPath);
ugi.doAs(new PrivilegedAction<Object>() {
@Override
public Object run() {
// access hdfs/hive metastore
}
});{code}
So that's why we may need a wrapper.

> Components: Connectors / Hive
> Reporter: luoyuxia
> Priority: Major
> Fix For: 1.16.0
>
>
> Currently, to access kerberos-enabled Hive cluster, users are expected to add
> key/secret in flink-conf. But it can only access one Hive cluster in one
> Flink cluster, we are also expected to support multi kerberos-enabled Hive
> clusters in one Flink cluster.
