Christina created FLINK-11021:
---------------------------------
Summary: 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
Affects Versions: 1.6.2
Environment: Scala 2.11.11, OpenJDK 1.8.0_192-b12
Reporter: Christina
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}
