Class QueryIdentifier

java.lang.Object

org.apache.hadoop.hive.llap.daemon.impl.QueryIdentifier

public final class QueryIdentifier
extends Object

An identifier for a query, which is unique. This is based on the AppId and dagId. At the moment, It's possible for Hive to use the same "hive.query.id" if a single query is split into stages - which prevents this identifier being used as the unique id. Not exposing getters to allow this to evolve - i.e. retain the uniqueness constraint.
