Satish Mittal commented on HIVE-6109:
-------------------------------------
As an example, suppose a table user_logs is partitioned by (year, month, day,
hour, minute, country) and stored at location "hdfs://hcat/data/user_logs".
Currently dynamic partitions for user_logs would get created at HDFS locations
in the fixed format
"hdfs://hcat/data/user_logs/year=2013/month=12/hour=06/minute=10/country=US".
However in our use-case this breaks other data pipeline applications which
expect the data to arrive in a different format:
"hdfs://hcat/data/user_logs/2013/12/06/10/US". There could be similar other
use-cases possible.

> Project: Hive
> Issue Type: Improvement
> Components: HCatalog
> Reporter: Satish Mittal
>
> Currently when dynamic partitions are created by HCatalog, the underlying
> directories for the partitions are created in a fixed 'Hive-style' format,
> i.e. root_dir/key1=value1/key2=value2/.... and so on. However in case of
> external table, user should be able to control the format of directories
> created for dynamic partitions.
