We are planning to drop table_references and only accept join chains in the
cube/dimension definitions.

> Key: LENS-454
> URL: https://issues.apache.org/jira/browse/LENS-454
> Project: Apache Lens
> Issue Type: Bug
> Components: cube
> Reporter: Angad Singh

> Consider a dimension X with the following dim_attribute:
> {noformat}
> <dim_attribute name="lastKnownLocation" type="LONG" description="not
> available currently">
> <ref_spec>
> <table_references>
> <table_reference
> column="lastKnownLocation" table="user_latest_location" />
> </table_references>
> </ref_spec>
> </dim_attribute>
> {noformat}
> Now consider the query:
> {noformat}
> lens-shell>prepQuery prepare --query "cube select
> user_latest_location.locationId from user j"
> 0a2c2c16-836f-4cd0-a3e6-ab5f5b38bb31
> lens-shell>prepQuery details --handle 0a2c2c16-836f-4cd0-a3e6-ab5f5b38bb31
> User query:cube select user_latest_location.locationId from user j
> Prepare handle:0a2c2c16-836f-4cd0-a3e6-ab5f5b38bb31
> User:anonymous
> Prepared at:Wed Mar 25 13:13:27 UTC 2015
> Selected driver :org.apache.lens.driver.hive.HiveDriver
> Driver query:SELECT ( user_latest_location . locationid ) FROM
> user.uh1_hdfs_dimtableA j WHERE ((((user_latest_location.dt = 'latest')) AND
> ((j.dt = 'latest'))
> {noformat}
> Lens is select a column from user_latest_location without joining it with
> dimtableA
