Hello Kylin Community,

I am stuck with setting up kylin and running sample cube building. I am getting class not
found exception for HCatInputFormat  in the "Extract Fact Table Distinct Columns" step of
kylin_sales_cube build.

I verified that hive-catalog jar(hive-hcatalog-core-1.1.0-cdh5.6.0.jar) is present in the
 hive_dependency also it is available in the path also.

I am using Kylin 1.5.0 and CDH 5.6 distribution on a single node.
