MERGE CUBE job failed in Step 2, throwing such exception:

Caused by: java.lang.IllegalStateException: Metadata uri : kylin_metadata_my_service@hdfs,path=viewfs://hadoop-footest/kylin/kylin_metadata_my_service/kylin-9583f16b-93cb-9461-a58c-43c848007972/kylin_sales_cube_clone_spark/metadata
looks like a file but it's neither a file nor a directory
at org.apache.kylin.common.KylinConfig.decideUriType(KylinConfig.java:162)
... 9 more
{code}
The metadataUrl is on hdfs, but decideUriType() method does not recognize it.

Thus throwing such exception.

Both MR and Spark engine are affected.

Would [~Wayne0101] please have a look? I see it's related to KYLIN-3471
