Aljoscha Krettek closed FLINK-8272.
-----------------------------------
Resolution: Not A Problem
Fix Version/s: (was: 1.4.0)
> 1.4 & Scala: Exception when querying the state
> ----------------------------------------------
>
> Key: FLINK-8272
> URL: https://issues.apache.org/jira/browse/FLINK-8272
> Project: Flink
> Issue Type: Bug
> Components: Queryable State
> Affects Versions: 1.4.0
> Environment: mac
> Reporter: Juan Miguel Cejuela
>
> With Flink 1.3.2 and basically the same code except for the changes in the
> API that happened in 1.4.0, I could query the state finely.
> With 1.4.0 (& scala), I get the exception written below. Most important line:
> {{java.util.concurrent.CompletionException:
> java.lang.IndexOutOfBoundsException: readerIndex(0) + length(4) exceeds
> writerIndex(0): PooledUnsafeDirectByteBuf(ridx: 0, widx: 0, cap: 0)}}
> Somehow it seems that the connection to the underlying buffer fails. Perhaps
> most informing is that, if I give a wrong {{JobId}} (i.e. one that is not
> running), I still get the same error. So I guess no connection succeeds.
> Also, to avoid possible serialization errors, I am just querying with a key
> of type {{String}} and, for testing, a dummy & trivial {{case class}}.
> I create the necessary types such as:
> {code}
> implicit val typeInformationString = createTypeInformation[String]
> implicit val typeInformationDummy = createTypeInformation[Dummy]
> implicit val valueStateDescriptorDummy =
> new ValueStateDescriptor("state", typeInformationDummy)}}
> {code}
> And then query the like such as:
> {code}
> val javaCompletableFuture = client
> .getKvState(this.flinkJobIdObject, this.queryableState, key,
> typeInformationString, valueStateDescriptorDummy)
> {code}
> Does anybody have any clue on this? Let me know what other information I
> should provide.
