Pratik Khadloya commented on HIVE-6589:
---------------------------------------

Thank you [~dharmendra0393] for taking this up.

This is a very important jira as the issue is faced by all companies. We are 
also having to maintain cron jobs just to create partitions after data is 
loaded and on top of that all alerts to make sure the job succeeds atleast once 
for a given partition. 

> Automatically add partitions for external tables

> 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}
