Subject Partitioning EXTERNAL TABLE without copying or moving files
Date Thu, 08 Dec 2011 20:46:35 GMT
Hi,

I am running Hive 0.7.0 with Hadoop 0.20.2.  I have one HDFS folder full of web server logs
dated back several months.

Is possible to partition an EXTERNAL TABLE without copying/moving files or altering the layout
of the directory?

For example, in HDFS, I have:

> /logs/log-2011-09-01
> /logs/log-2011-09-02
>   …
> /logs/log-2011-12-01

I'd like to know if it's possible to partition the EXTERNAL TABLE by date without having to
create subdirectories:

> /logs/2011-09-01/log-2011-09-01
> /logs/2011-09-02/log-2011-09-02
>   …
> /logs/2011-12-01/log-2011-12-01

Is it possible?

Thanks,
Vince
