---------------------------------------------------------------
This issue needs to be fixed ASAP. The fact that this has been open and
unaddressed since 2014 is frankly ridiculous, especially given how many
services rely on Hive's table indexes and use external tables.

> Automatically add partitions for external tables
> ------------------------------------------------
>
> Key: HIVE-6589
> URL: https://issues.apache.org/jira/browse/HIVE-6589
> Project: Hive
> Issue Type: New Feature
> Affects Versions: 0.14.0
> Reporter: Ken Dallmeyer
> Assignee: Dharmendra Pratap Singh
>
> I have a data stream being loaded into Hadoop via Flume. It loads into a date
> partition folder in HDFS. The path looks like this:
> {code}/flume/my_data/YYYY/MM/DD/HH
> /flume/my_data/2014/03/02/01
> /flume/my_data/2014/03/02/02
> /flume/my_data/2014/03/02/03{code}
> On top of it I create an EXTERNAL hive table to do querying. As of now, I
> have to manually add partitions. What I want is for EXTERNAL tables, Hive
> should "discover" those partitions. Additionally I would like to specify a
> partition pattern so that when I query Hive will know to use the partition
> pattern to find the HDFS folder.
> So something like this:
> {code}CREATE EXTERNAL TABLE my_data (
> col1 STRING,
> col2 INT
> )
> PARTITIONED BY (
> dt STRING,
> hour STRING
> )
> LOCATION
> '/flume/mydata'
> TBLPROPERTIES (
> 'hive.partition.spec' = 'dt=$Y-$M-$D, hour=$H',
> 'hive.partition.spec.location' = '$Y/$M/$D/$H',
> );
> {code}
