Review Comment:
> causes the error
The principal in this format: user/host, causes the error.
When submitting a task, the principal specified through the --conf
spark.kerberos.principal parameter is in the format of user/host@realm.
However, in the HiveMetaStore$HMSHandler.get_delegation_token method of the
HMS, the format of the owner parameter is user/host without the @realm part.
This is where the problem arises.
