Re: Is kylin support kerberos while using cube connecting to HBASE?

Thank you for your reply.

Below are what I have done:
1. I have set the kerberos token for the user and put the keytab under home
directory.
2. I have made a crontab to refresh the keytab
3. I set kylin.properties like following:
    >kylin.env.hadoop-conf-dir=/home/kylin/hadoop-conf
    >kylin.engine.spark-conf.spark.principal=kylin/kylin@MYSERVER.COM
    >kylin.engine.spark-conf.spark.keytab=/home/kylin/kylin.keytab
    >kylin.engine.spark-conf.spark.yarn.keytab=/home/kylin/kylin.keytab
    >kylin.engine.spark-conf.spark.yarn.principal=kylin/kylin@MYSERVER.COM
    >kylin.engine.spark-conf.spark.yarn.security.tokens.hbase.enabled=true
4. I put all my hadoop setting files under '/home/kylin/hadoop-conf'
5. I set hbase-site.xml like followling:
      <property>
          <name>hbase.security.authentication</name>
          <value>kerberos</value>
      </property>

Is there anything I should do more to make it work?
Looking forward to your reply, thank you!

There were some similar reportings in Kylin community but seems no
resolution. You can do a search here.

Hi, I have done it. But after a period of time, kylin can't connect with hive
expect restart. The error is /'Caused by: GSSException: No valid credentials
provided (Mechanism level: Failed to find any Kerberos tgt)' / I have
configured a scheduled task with crontab to refresh tgt cache and I can get
connect using hive commond. Except that, I try to use kdestory to delete the
cache and then refresh, kylin can't connect with hive too. What is the
reason for this? Have you met?
