stats19.q is failing on the current trunk?

Always get this diff:

[junit] diff -a 
/home/zhenxiao/Code/hive/build/ql/test/logs/clientpositive/stats19.q.out 
/home/zhenxiao/Code/hive/ql/src/test/results/clientpositive/stats19.q.out
    [junit] 21,22c21,22
    [junit] < Stats prefix is hashed: false
    [junit] < Stats prefix is hashed: false
    [junit] ---
    [junit] > Stats prefix is hashed: true
    [junit] > Stats prefix is hashed: true

    [junit] < Stats prefix is hashed: false
    [junit] ---
    [junit] > Stats prefix is hashed: true
    [junit] > Stats prefix is hashed: true

Will file a Jira if other people found it, too.

Thanks,
