Description

• Modifies COMPUTE STATS for the non-incremental case. 
  The change allows an optional column list to be specified for a given table. 
  Example: compute stats my_table (col_1, col_2) ... 
  The column list specifies which columns will have stats computed. If a column is specified that is invalid, an error will be returned. Invalid columns are ones that are not part of the specified table, are a complex type, or for hdfs tables, are a partitioning key. If no columns are specified, e.g., "( )", stats will not be computed for any columns.
