Sean Owen resolved SPARK-3712. ------------------------------ Resolution: Won't Fix Target Version/s: (was: 1.1.1, 1.2.0) Withdrawn in the PR by the proposer. > add a new UpdateDStream to update a rdd dynamically > --------------------------------------------------- > > Key: SPARK-3712 > URL: https://issues.apache.org/jira/browse/SPARK-3712 > Project: Spark > Issue Type: Improvement > Components: Streaming > Reporter: uncleGen > Priority: Minor > > Maybe, we can achieve the aim by using "forEachRdd" function. But I feel > weird in this way, because I need to pass a closure, like this: > val baseRdd = ... > var updatedRDD = ... > val inputStream = ... > val func = (rdd: RDD[T], t: Time) => { > updatedRDD = baseRDD.op(rdd) > } > inputStream.foreachRDD(func _) > In my PR, we can update a rdd like: > val updateStream = inputStream.updateRDD(baseRDD, func).asInstanceOf[T, > V, U] > and obtain the updatedRDD like this: > val updatedRDD = updateStream.getUpdatedRDD -- 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
