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

All Implemented Interfaces:

NodeProcessor

public class ProcessAnalyzeTable
extends Object
implements NodeProcessor

ProcessAnalyzeTable sets up work for the several variants of analyze table (normal, no scan, partial scan.) The plan at this point will be a single table scan operator.
