Description
I am trying to enable system cubes for the Dashboard using Kylin version 2.6.4 The tables are created correctly and the cube builds successfully but there is no query or job data on the dashboard, it shows 0.
We use Azure storage for Hive(wasb:// file system). I can see that there is no data being updated on the Hive_Metrics tables in Azure. In Kylin logs I see the below error
2020-03-12 20:02:41,790 ERROR [metrics-blocking-reservoir-scheduler-0] hive.HiveReservoirReporter:119 : Wrong FS: wasb://****.blob.core.windows.net/hive/warehouse/kylin.db/hive_metrics_query_cube_qa/kday_date=2020-03-12, expected: hdfs://****-prod-bn01

I checked the hive configs and it has the warehouse metastore dir correctly pointing to azure. I found another thread with similar problem where they are trying to use S3 instead of hdfs. http://apache-kylin.74782.x6.nabble.com/jira-Created-KYLIN-4385-KYLIN-system-cube-failing-to-update-table-when-run-on-EMR-with-S3-as-storageS-td14234.html
I also followed the recommendations here https://www.mail-archive.com/user@kylin.apache.org/msg04347.html and enabled all the necessary config values.
Is this a bug in Kylin or a configuration issue on my cluster? Any help or guidance is appreciated.
