Hi,
Continuing the discussion from the mailing list, I was able to go past the
NettyConfig problem once I ran Flink in cluster mode ( I would still like to
know if there is a way to run in local mode so that I can avoid running SBT
assembly every time ).
But now I am stuck at error message "KvState does not hold any state for
key/namespace." which I believe is because of my KeySerializer. Since I am
running the QueryClient as a separate application, I don't have access to my
queryableState to call `queryableState.getKeySerializer`
My key is a tuple of (Long,String) and this is the naive serializer that I
wrote (which is probably wrong and I have never written a serializer before)
```
class KeySerializer extends TypeSerializerSingleton[(Long,String)]{
private val EMPTY: (Long,String) = (0,"")
override def createInstance(): (Long, String) = EMPTY
override def getLength: Int = return 2;
override def canEqual(o: scala.Any): Boolean = return
o.isInstanceOf[(Long,String)]
override def copy(t: (Long, String)): (Long, String) = t
override def copy(t: (Long, String), t1: (Long, String)): (Long,
String) = t
override def copy(dataInputView: DataInputView, dataOutputView:
DataOutputView): Unit = {
dataOutputView.writeLong(dataInputView.readLong())
StringValue.copyString(dataInputView,dataOutputView)
}
override def serialize(t: (Long, String), dataOutputView:
DataOutputView): Unit = {
dataOutputView.writeLong(t._1)
StringValue.writeString(t._2,dataOutputView)
}
override def isImmutableType: Boolean = true
override def deserialize(dataInputView: DataInputView): (Long, String)
= {
val l = dataInputView.readLong()
val s = StringValue.readString(dataInputView)
(l,s)
}
override def deserialize(t: (Long, String), dataInputView:
DataInputView): (Long, String) = deserialize(dataInputView)
}
```
Can you tell me what I am doing wrong here? Thanks!
