Get race condition in hive with script_pipe.q ( the same as HIVE-1491)
Hi,All
I got the same error message described in [HIVE-1491] (
https://issues.apache.org/jira/browse/HIVE-1491) when ran script_pipe.q on
Open JDK.
Will hive plan to resolve this race condition?

I tried to re-produce it:
1. create table src with two columns: key and value
2. run the following queries:
SELECT TRANSFORM(key, value) USING 'head -n 1' FROM src;    // PASS
SELECT TRANSFORM(key, value) USING 'head -n 1' as a,b,c,d FROM src;
//PASS

SELECT TRANSFORM(key, value, key, value) USING 'head -n 1' FROM src;
//PASS
SELECT TRANSFORM(key, value, key, value) USING 'head -n 1' as a,b,c,d FROM
src;    //PASS

SELECT TRANSFORM(key, value, key, value, key, value) USING 'head -n 1' FROM
src;    //FAILED
SELECT TRANSFORM(key, value, key, value, key, value) USING 'head -n 1' as
a,b,c,d FROM src;    //FAILED
