Flink Jira Bot updated FLINK-11021:
-----------------------------------
Priority: Minor (was: Major)
> ZoneOffset objects don't appear to be serialized correctly
> ----------------------------------------------------------
>
> Key: FLINK-11021
> URL: https://issues.apache.org/jira/browse/FLINK-11021
> Project: Flink
> Issue Type: Bug
> Components: API / Type Serialization System
> Affects Versions: 1.6.2
> Environment: Scala 2.11.11, OpenJDK 1.8.0_192-b12
> Reporter: Christina
> Priority: Minor
> Labels: auto-deprioritized-major
> Attachments: TimezoneStreamProcessor.scala

> In Flink 1.6.2 ZoneOffset objects are not being serialized correctly: they
> are turned into `null` when serialized in a Flink job. I've attached a basic
> sample job that illustrates the problem along with a few sbt console commands
> (below) that also exhibit the problem.
>
> {code:java}
> import org.apache.flink.streaming.api.scala.StreamExecutionEnvironment
> import java.time._
> import java.time.temporal.ChronoUnit
> val env = StreamExecutionEnvironment.createLocalEnvironment(1)
> val UTCZoneId = ZoneId.of("UTC")
> val UTCZoneOffset = ZoneOffset.UTC
> case class MyTime(
> timestamp: ZonedDateTime,
> zoneOffset: ZoneOffset
> ) extends Serializable
> val now = MyTime(ZonedDateTime.now(UTCZoneId).truncatedTo(ChronoUnit.MILLIS),
> UTCZoneOffset)
> val mytimeTypeInfo =
> org.apache.flink.api.common.typeinfo.TypeInformation.of(classOf[MyTime])
> val ser = mytimeTypeInfo.createSerializer(env.getConfig)
> val out = new org.apache.flink.core.memory.ByteArrayDataOutputView()
> val serialized = ser.serialize(now, out)
> val bytes = out.toByteArray
> val in = new org.apache.flink.core.memory.ByteArrayDataInputView(bytes)
> val deserialized = ser.deserialize(in)
> println(s"""
> before serializaton: $now
> after serialization: $deserialized
> """){code}
