							 Dear @DianaTorres @yagoaparecidoti @james_jones   Many thanks for your kind guidance. I was able to successfully connect to the Hive Metastore following your instructions. However, I encountered some issues when connecting to HDFS. Although, I have configured the settings in accordance with the documentation, the system reports that certain parameters are 'not used'.  I have configured the file as follows:  hive.config.resources=core-site.xml,hdfs-site.xml  hive.hdfs.authentication.type=KERBEROS  hive.hdfs.impersonation.enabled=true  hive.hdfs.trino.principal=trino@MYREALM  hive.hdfs.trino.keytab=trino.keytab  could you kindly advise whether this issue may be caused by incorrect parameter settings, or if HDFS requires a different authentication method?  Please let me know if there are any files I should provide. And thank you in advance for your support.

							 Dear Support Team,  I hope this message finds you well.  I am currently working on setting up Trino to query data from Hive. However, I am encountering difficulties related to Kerberos authentication.  Despite following available documentation, I have not been able to successfully connect to the Hive. I think there is something wrong with my KERBEROS settings. When I use telnet or ping, I can connect to HIVE correctly, but when I use trino CLI,  it shows that it is socket is closed by peer.   I would appreciate your guidance on:1. I would like to ask whether I need to set up Kerberos separately for trino connection? 2. How can I get relevant information about kerberos authentication, such as keytab.  Here are some details about my setup:(I think maybe at least this information is needed, but I don't know where to get them as following)1.hive.metastore.client.principal=trino.example.com 2.hive.metastore.client.keytab=trino.keytab .  Please let me know if there are any files I should provide. And thank you in advance for your support.
