I asked the question to confirm workaround. We also execute periodically kinit.
Additionaly, We investigated the behavior of Kylin and found an inadequate one. I have attatched the result. When we try "Load Hive Table", Kylin Server dose not reload auth-info. I filed this issue. https://issues.apache.org/jira/browse/KYLIN-2683 ________________________________ 差出人: ShaoFeng Shi <[email protected]> 送信日�r: 2017年5月3日 16:26:21 宛先: user 件名: Re: How can we refresh auth token for data source? I have same comment as Yu Feng; Kylin supports kerberos authentication seamlessly; You just need automatically run kinit periodically (with the same Linux user) to ensure the token will not expire. I know many users are running in this way. If it doesn't work in your side, please share more information. 2017-05-03 9:41 GMT+08:00 yu feng <[email protected]<mailto:[email protected]>>: we always start a crontab job to refresh the keberos token periodically. 2017-05-02 17:07 GMT+08:00 Kanta Kuramoto <[email protected]<mailto:[email protected]>>: We use kerberized hadoop cluster for datasource. It seems Kylin server loads auth token only when it starts, so after the token is expired, Kylin server can not load metadata from HS2. Can we refresh the auth token? -- Best regards, Shaofeng Shi 史少锋
