Aleksei Statkevich updated HIVE-13372:
--------------------------------------
    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:
{code}
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;
{code}

When we ran the following query, 
{code}
SELECT
    CONCAT(STRING_LEN(x), ":", STRING_LEN_PLUS_ONE(x), ":", STRING_LEN_PLUS_TWO(x)) a
FROM macro_test
SORT BY a DESC;
{code}

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.
