Apache Spark reassigned SPARK-25522: ------------------------------------ Assignee: Dilip Biswal (was: Apache Spark) > Improve type promotion for input arguments of elementAt function > ----------------------------------------------------------------- > > Key: SPARK-25522 > URL: https://issues.apache.org/jira/browse/SPARK-25522 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.4.0 > Reporter: Dilip Biswal > Assignee: Dilip Biswal > Priority: Major > Fix For: 2.4.0 > > > In ElementAt, when first argument is MapType, we should coerce the key type > and the second argument based on findTightestCommonType. This is not > happening currently. > Also, when the first argument is ArrayType, the second argument should be an > integer type or a smaller integral type that can be safely casted to an > integer type. Currently we may do an unsafe cast. > {code:java} > spark-sql> select element_at(array(1,2), 1.24); > 1{code} > {code:java} > spark-sql> select element_at(map(1,"one", 2, "two"), 2.2); > two{code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
