[jira] [Updated] (SPARK-17298) Require explicit CROSS join for cartesian products by default
[ https://issues.apache.org/jira/browse/SPARK-17298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Srinath updated SPARK-17298: Description: Require the use of CROSS join syntax in SQL (and a new crossJoin DataFrame API) to specify explicit cartesian products between relations under the default configuration (spark.sql.crossJoin.enabled = false). By cartesian product we mean a join between relations R and S where there is no join condition involving columns from both R and S. If a cartesian product is detected in the absence of an explicit CROSS join, an error must be thrown. Turning on the spark.sql.crossJoin.enabled configuration flag will disable this check and allow cartesian products without an explicit cross join. was: Require the use of CROSS join syntax in SQL (and a new crossJoin DataFrame API) to specify explicit cartesian products between relations under the default configuration with spark.sql.crossJoin.enabled = false.
