Dear all, First of all, I am sorry if I sent this message twice, I received no confirmation of my previous email actually reaching the mailing list.
For my project I want to be able to access the HiveRelNodes for some extended semantic analysis. By extending the hookcontext and adding a new hook I have been able to access them serverside. To gain access to them from a client perspective I was thinking about serializing them and then deserialize them from the client (perhaps by storing the serialized form in a table). Since the RelNode and HiveRelNode classes do not implement the Serializable interface I thought maybe I could use the RelJsonWriter and RelJsonReader instead. However the RelJsonWriter is not able to convert the HiveRelNodes into a json format. Would anyone perhaps know of a different solution to serializing and deserializing these HiveRelNodes? With kind regards, Mark
