Apache Spark reassigned SPARK-14390: ------------------------------------ Assignee: (was: Apache Spark) > Make initialization step in Pregel optional. > -------------------------------------------- > > Key: SPARK-14390 > URL: https://issues.apache.org/jira/browse/SPARK-14390 > Project: Spark > Issue Type: Improvement > Components: GraphX > Affects Versions: 2.1.0 > Reporter: Anderson de Andrade > Priority: Minor > > Suppose a sendMsg function depends on the state of a edge's vertices to send > messages, and those Pregel messages update such state. In this scenario, > initialMsg will initially enforce the same message on all vertices, > effectively removing a custom initialization one may have per vertex. > To deal with this situation, we must define a dummy initMsg (i.e. None), and > all Pregel functions must be modified to handle this type of message. A > simpler and less cumbersome solution is to make initMsg and the > initialization step in Pregel optional. -- 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
