> In order to use proxy user to access hive metastore server with kerberos, I
> set HADOOP_PROXY_USER = proxy user.
> this is the code of HiveMetaStoreClient
> !image-2023-03-14-20-51-32-317.png|width=606,height=393!
> but when I run a spark job with hive metatsore client, the connection to
> hive metatsore server always close
> !image-2023-03-14-20-53-40-132.png|width=687,height=375!
> and I notice that some log before close :
> {color:#ff0000}Mestastore configuration hive.metastore.token.signature
> changed from DelegationTokenForHiveMetaStoreServer to{color}
> so we can find why the connection close always, hive metatsore client will
> compare currentMetaVars with hiveconf
> !image-2023-03-14-20-56-00-757.png|width=903,height=463!
> but if we set HADOOP_PROXY_USER and init hive metatsore client, the
> ConfVars.METASTORE_TOKEN_SIGNATURE always is set
> !image-2023-03-14-21-00-18-049.png|width=905,height=592!
> so I think this solutions can fix the bug:
> ConfVars.METASTORE_TOKEN_SIGNATURE is no need to check in hive metatsore
> client
> !image-2023-03-14-21-03-52-764.png|width=905,height=606!
> obviously that is no more close
