> 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.

>
> 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.
