Kapil Singh commented on SPARK-16894: ------------------------------------- This is not about selecting first n elements/columns from a Row. It's for selecting first n elements of an array type column. So for every record/Row the input column has some m elements but the result column has only first n elements of the input column. This operation is similar to scala collection's take operation. The scope of the operation is cell values and not Row. > take function for returning the first n elements of array column > ---------------------------------------------------------------- > > Key: SPARK-16894 > URL: https://issues.apache.org/jira/browse/SPARK-16894 > Project: Spark > Issue Type: New Feature > Components: SQL > Reporter: Kapil Singh > > take(inputArray, n) > Returns array containing first n elements of inputArray -- 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
