Description

Trying to override HiveContext.analyzer will give the following compilation error:

Error:(51, 36) overriding lazy value analyzer in class HiveContext of type org.apache.spark.sql.catalyst.analysis.Analyzer{val extendedResolutionRules: List[org.apache.spark.sql.catalyst.rules.Rule[org.apache.spark.sql.catalyst.plans.logical.LogicalPlan]]};
 lazy value analyzer has incompatible type
  override protected[sql] lazy val analyzer: Analyzer = {
                                   ^

That is because the type changed inadvertedly when omitting the type declaration of the return type.
