hi,

We setup a new hive 0.9 client, Found some sql did not work, for example

hive> create table t1(a int) partitioned by ( dt int );
OK
Time taken: 0.097 seconds
hive> load data local inpath '/tmp/t' into table t1 partition (dt=111);
Copying data from file:/tmp/t
Copying file: file:/tmp/t
Loading data to table default.t1 partition (dt=111)
OK
Time taken: 0.375 seconds
hive> show partitions t1;
OK
dt=111
Time taken: 0.108 seconds
hive> alter table t1 drop partition ( dt=111 );
FAILED: Error in semantic analysis: Partition not found dt = 111
hive> alter table t1 drop partition ( dt='111' );
FAILED: Error in semantic analysis: Partition not found dt = '111'
So, how to delete the partition?

Hello wd,
Try this one... I am not sure about this
ALTER TABLE t1 DROP PARTITION(dt = '111')

No problem, thanks for your reply.
I'm very curious why this didn't work, this sql come from hive wiki.
The metadata is store in postgres, does it matter?

You should look at hive log and find exact exception. That will give you a
hint.

Nothing output in hive history file, is there an other log file or an
option to output detail log ?

Still no useful output. But we found the problem.

When the partition col type is int, it can't be droped. After change
it to string, it can be droped.

Hi,
We used to use integer partitioning for 2 columns, "year_month_day"
and "hour"

When it came to dropping 1 partition for an hour for a particular day, it
seemed to drop all of the hour partitions for the day.

IMO it's a bug. We just moved to using text

It's too bad.
I've file a issue at hive jira, https://issues.apache.org/jira/browse/HIVE-3069.
