Subject: Re: ALTER TABLE DROP PARTITION not working on S3
Hi Richard,
could you please check if your table is EXTERNAL?
You can see it with a "DESCRIBE FORMATTED table_name ;"
That's what external tables are for, they don't delete underlying data when you
drop them.

I think that someone put a file in there manually. Would that prevent Hive from
dropping the partition. I also did a "drop table" and the s3 object keys
persisted.

Subject: ALTER TABLE DROP PARTITION not working on S3
Hi,
I have a Hive managed table on S3, "api_measurements". I've tried dropping a
partition like so:
hive> alter table api_measurements drop if exists
partition(daydate='2018-04-04', epoch=1522876500);
Dropped the partition daydate=2018-04-04/epoch=1522876500
OK
Time taken: 2.109 seconds
Yet the data is still on S3. Because object keys on S3 are always strings, I
also tried this:
hive> alter table api_measurements drop partition(daydate='2018-04-04',
epoch='1522876500');
OK
Time taken: 0.135 seconds
Yet the object keys and data are still there. I assume that Im missing
something really simple. Can anyone shed some light on this?
Thanks
