Yes, the idea is almost the same -- LLAP daemons can accept tasks from
different Tez AMs, whereas MR3 containers can accept tasks from different
DAGs. A minor difference is that in the case of MR3, a single shared AM can
manage multiple concurrent DAGs. As a result, there is no need to start a
new
¯\_(ツ)_/¯

Indeed.
If I remember correctly, s3
Indeed.
If I remember correctly, s3 does not really have the concept of "folder"
like HDFS has, and Hive sort of makes up for it by creating a descriptor
file
where the partition "folder" is supposed to be. Maybe this is what is
missing here.
Perhaps you could try doing a "MSCK REPAIR TABLE
Leaving the column list out, here you go:
# Detailed Table Information

No definitely internal. It's loaded from an external table.

Hi Richard,
could you please check if
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.

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
