> Iceberg uses "null" and does not use the configuration key
> "hive.exec.default.partition.name" for default partitions.

> Key: HIVE-26732
> URL: https://issues.apache.org/jira/browse/HIVE-26732
> Project: Hive
> Issue Type: Bug
> Components: Iceberg integration
> Affects Versions: 4.0.0-alpha-1
> Reporter: Sungwoo Park
> Priority: Major
>
> When creating an Iceberg table from an existing ORC table with "insert
> overwrite", the directory corresponding to the default partition uses "null"
> instead of the value for the configuration key
> "hive.exec.default.partition.name".
> For example, we create an Iceberg table from an existing ORC table
> tpcds_bin_partitioned_orc_1000.catalog_sales:
> {code:java}
> create table catalog_sales ( cs_sold_time_sk bigint, cs_ship_date_sk
> bigint, cs_bill_customer_sk bigint, cs_bill_cdemo_sk bigint,
> cs_bill_hdemo_sk bigint, cs_bill_addr_sk bigint, cs_ship_customer_sk
> bigint, cs_ship_cdemo_sk bigint, cs_ship_hdemo_sk bigint,
> cs_ship_addr_sk bigint, cs_call_center_sk bigint, cs_catalog_page_sk
> bigint, cs_ship_mode_sk bigint, cs_warehouse_sk bigint, cs_item_sk
> bigint, cs_promo_sk bigint, cs_order_number bigint, cs_quantity
> int, cs_wholesale_cost double, cs_list_price double, cs_sales_price
> double, cs_ext_discount_amt double, cs_ext_sales_price double,
> cs_ext_wholesale_cost double, cs_ext_list_price double, cs_ext_tax
> double, cs_coupon_amt double, cs_ext_ship_cost double, cs_net_paid
> double, cs_net_paid_inc_tax double, cs_net_paid_inc_ship double,
> cs_net_paid_inc_ship_tax double, cs_net_profit double) partitioned by
> (cs_sold_date_sk bigint) STORED BY ICEBERG stored as orc;
> insert overwrite table catalog_sales select * from
> tpcds_bin_partitioned_orc_1000.catalog_sales;
> {code}
> Iceberg creates a directory for the default partition like:
> {code:java}
> /hive/warehouse/tpcds_bin_partitioned_orc_1000_iceberg.db/catalog_sales/data/cs_sold_date_sk=null{code}
> which should be:
> {code:java}
> /hive/warehouse/tpcds_bin_partitioned_orc_1000_iceberg.db/catalog_sales/data/cs_sold_date_sk=__HIVE_DEFAULT_PARTITION__{code}
>
