> Consider the following testcase:
> create table tst5 (key string, value string) partitioned by (ds string)
> stored as rcfile;
> insert overwrite table tst5 partition (ds='1') select * from src;
> insert overwrite table tst5 partition (ds='2') select * from src;
> insert overwrite table tst5 partition (ds='3') select * from src;
> alter table tst5 stored as sequencefile;
> insert overwrite table tst5 partition (ds='4') select * from src;
> insert overwrite table tst5 partition (ds='5') select * from src;
> insert overwrite table tst5 partition (ds='6') select * from src;
> alter table tst5 set serde
> 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe';
> insert overwrite table tst5 partition (ds='7') select * from src;
> insert overwrite table tst5 partition (ds='8') select * from src;
> insert overwrite table tst5 partition (ds='9') select * from src;
> The following query works fine:
> select key + key, value from tst5 where ((ds = '4') or (ds = '1'));
> since both the partitions use ColumnarSerDe
> But the following query fails:
> select key + key, value from tst5 where ((ds = '4') or (ds = '1') or
> (ds='7'));
> since different serdes are used.
