Subject [jira] Created: (HIVE-545) Use ArrayList instead of Vector in single-threaded Hive code
Date Sat, 06 Jun 2009 00:58:07 GMT
Use ArrayList instead of Vector in single-threaded Hive code
------------------------------------------------------------

                 Key: HIVE-545
                 URL: https://issues.apache.org/jira/browse/HIVE-545
             Project: Hadoop Hive
          Issue Type: Improvement
    Affects Versions: 0.4.0
            Reporter: Zheng Shao


Most of the Hive code is single-threaded, but sometimes we are using Vector instead of the
more efficient ArrayList.

See http://java.sun.com/j2se/1.5.0/docs/api/java/util/ArrayList.html
"This class (ArrayList) is roughly equivalent to Vector, except that it is unsynchronized."
