Shixiong Zhu resolved SPARK-13121. ---------------------------------- Resolution: Fixed Fix Version/s: 2.0.0 > java mapWithState mishandles scala Option > ----------------------------------------- > > Key: SPARK-13121 > URL: https://issues.apache.org/jira/browse/SPARK-13121 > Project: Spark > Issue Type: Bug > Components: Java API, Streaming > Affects Versions: 1.6.0 > Reporter: Gabriele Nizzoli > Priority: Critical > Fix For: 1.6.1, 2.0.0 > > > in Spark Streaming, java mapWithState that uses Function3 has a bug in the > convertion from a scala Option to a java Optional. In the conversion, the > code in `StateSpec.scala`, line 222 is > `Optional.fromNullable(v.get)`. This fails if `v`, an `Option`, is `None`, > better to use `JavaUtils.optionToOptional(v)` instead. > Workaround is to use the Function4 call to mapWithState. This call has the > right conversion. -- 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
