> Key: KYLIN-2817
> URL: https://issues.apache.org/jira/browse/KYLIN-2817
> Project: Kylin
> Issue Type: Bug
> Components: Environment
> Affects Versions: v2.0.0
> Environment: CDH：5.7.1

> In building kylin read and write separation environment, I encountered some
> Kerberos permissions problems.
> The Kylin's environment is as follows:
> CDH 5.7.1 Cluster A: Yarn,HDFS,Hive. HDFS is HA, Nameservice is nn-idc.
> CDH 5.7.1 Cluster B: Yarn,HDFS,HBase,Kylin，HDFS is HA, Nameservice is kylin-ns
> Cluster A and Cluster B use a common KDC.
> When I use kylin to build the cube, the error as following:
> #19 Step Name: Convert Cuboid Data to HFile
> java.io.IOException: Failed to run job : Failed to renew token: Kind:
> HDFS_DELEGATION_TOKEN, Service: ha-hdfs:kylin-ns, Ident:
> (HDFS_DELEGATION_TOKEN token 12 for kylin_manager_user)

> The problem is similar to that on Yarn's issues:
> https://issues.apache.org/jira/browse/YARN-3021
> So I think that Apache Kylin supports the environment of reading and writing
> separation. How can I solve this problem and configure it?
