If that is the case it sounds like a bug… From: Jary Du <jary...@gmail.com<mailto:jary...@gmail.com>> Reply-To: "user@hive.apache.org<mailto:user@hive.apache.org>" <user@hive.apache.org<mailto:user@hive.apache.org>> Date: Thursday, August 20, 2015 at 08:56 To: "user@hive.apache.org<mailto:user@hive.apache.org>" <user@hive.apache.org<mailto:user@hive.apache.org>> Subject: Re: HiveServer2 & Kerberos
My understanding is that it will always ask you user/password even though you don’t need them. It is just the way how hive is setup.

Loïc CHANEL Engineering student at TELECOM Nancy Trainee at Worldline - Villeurbanne 2015-08-19 17:51 GMT+02:00 Jary Du <jary...@gmail.com<mailto:jary...@gmail.com>>: For Beeline connection string, it should be "!connect jdbc:hive2://<host>:<port>/<db>;principal=<Server_Principal_of_HiveServer2>”. Please make sure it is the hive’s principal, not the user’s. And when you kinit, it should be kinit user’s keytab, not the hive’s keytab.

So, as I can make klist before launching beeline and having a good result, the problem does not come from this. Thanks a lot for your response though. Do you have another idea ? Loïc CHANEL Engineering student at TELECOM Nancy Trainee at Worldline - Villeurbanne 2015-08-19 17:42 GMT+02:00 Jary Du <jary...@gmail.com<mailto:jary...@gmail.com>>: "The Beeline client must have a valid Kerberos ticket in the ticket cache before attempting to connect." (http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.3/bk_dataintegration/content/ch_using-hive-clients-examples.html) So you need kinit first to have the valid Kerberos ticket int the ticket cache before using beeline to connect to HS2.
