Xiao Li resolved SPARK-7611. ---------------------------- Resolution: Fixed > Support HashJoin if the join condition uses eqNullSafe/<=> > ---------------------------------------------------------- > > Key: SPARK-7611 > URL: https://issues.apache.org/jira/browse/SPARK-7611 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 1.3.1 > Reporter: David Tolnay > > Currently ExtractEquiJoinKeys only looks for EqualTo, not EqualNullSafe. So > if your join condition uses eqNullSafe/<=> instead of equalTo/===, you end up > with the CartesianProduct strategy instead of HashJoin. > This requires many changes under org.apache.spark.sql.execution.joins, where > code assumes rows can only join "if (!key.anyNull)". -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
