Each dynamic partition column must be present in the custom location path in the format ${column_name}, and the custom location path must consist of all dynamic partition columns. Other valid custom path strings include:

  • data/${year}/${month}/${day}/${country}
  • ${year}­‐${month}­‐${day}/country=${country}

  • output/yr=${year}/mon=${month}/day=${day}/geo=${country}

See HCatalog Configuration Properties for another example. Also see the PDF attachment to HIVE-6019 for details of the implementation.
