[impala-user] Why function will be lost when restart service?

I have created some function in impala, why these function will be lost when restart impala service ?



Unfortunately these UDFs are not able to be persisted in the Hive
metastore so they are maintained in the catalog server's memory. When you restart the catalog server, the functions need to be
re-registered. We will be adding a persistent Impala metadata store in an upcoming release, at which point this will no longer be necessary.



Which release will support persistent function data?  



I don't think we've committed to a particular release for this feature yet.



 We have a lot of functions in my clusters, we must re-create these functions when restart impala, this is a torturous solution. What method can automatically execute some script to create functions after restart the impala service.
