Class OptimizeTezProcContext

java.lang.Object
  org.apache.hadoop.hive.ql.parse.OptimizeTezProcContext

All Implemented Interfaces:

NodeProcessorCtx

public class OptimizeTezProcContext
extends Object
implements NodeProcessorCtx

OptimizeTezProcContext. OptimizeTezProcContext maintains information about the current operator plan as we walk the operator tree to do some additional optimizations on it.
