      Description

      When multiple macros are used in one column, results of the later ones are over written by that of the first.

      For example:
      Suppose we have created a table called macro_test with single column x in STRING type, and with data as:
      "a"
      "bb"
      "ccc"

      We also create three macros:

      CREATE TEMPORARY MACRO STRING_LEN(x string) length(x);
      CREATE TEMPORARY MACRO STRING_LEN_PLUS_ONE(x string) length(x)+1;
      CREATE TEMPORARY MACRO STRING_LEN_PLUS_TWO(x string) length(x)+2;
      

      When we ran the following query,

      SELECT
          CONCAT(STRING_LEN(x), ":", STRING_LEN_PLUS_ONE(x), ":", STRING_LEN_PLUS_TWO(x)) a
      FROM macro_test
      SORT BY a DESC;
      

      We get result:
      3:3:3
      2:2:2
      1:1:1

      instead of expected:
      3:4:5
      2:3:4
      1:2:3

      Currently we are using Hive 1.2.1, and have applied both HIVE-11432 and HIVE-12277 patches.
