--------------------------------------------------------------
Please let me know if there are any updates on this issue or any workarounds to
it. Since Flume is used to stream into hdfs, it would be great if we do not
have to run a separate batch job to detect partitions for hive table. Any help
appreciated!

> 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
> Priority: Major
>
> 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}
