how to select data from hive with specific partition?
===

everyone. here are the interactions with the hive:

    hive> show partitions TABLENAME
    pt=2012.07.28.08/is_complete=1
    pt=2012.07.28.09/is_complete=1
    pt=2012.07.28.10/is_complete=1
    pt=2012.07.28.11/is_complete=1
    hive> select * from TABLENAME where pt='2012.07.28.10/is_complete=1' limit 1;
    OK
    Time taken: 2.807 seconds
    hive> select * from TABLENAME where pt='2012.07.28.10' limit 1;
    OK

    Time taken: 3.8 seconds
    hive>

My question is that why the first select can't get the data?
