Sun Rui closed SPARK-10047. --------------------------- Resolution: Implemented > Improve the implementation of collect() on DataFrame in SparkR > -------------------------------------------------------------- > > Key: SPARK-10047 > URL: https://issues.apache.org/jira/browse/SPARK-10047 > Project: Spark > Issue Type: Improvement > Components: SparkR > Reporter: Sun Rui > > currently in SparkR, collect() on a DataFrame collects the data within the > DataFrame into a local data.frame. R users are used to using data.frame. > However, collect() currently can't collect data of nested types from a > DataFrame because: > 1. The serializer in JVM backend does not support nested types; > 2. collect() in R side assumes each column is of simple atomic type that can > be combinded into a atomic vector -- 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
