Partitioned Cloudera Impala on premise extract tables cannot be updated

Tables in Cloudera Impala that are both partitioned and set as extract targets cannot be updated directly. This prevents operations such as dropping or adding new partitions.

Workaround:

Move the data to a new table that supports altering commands. Then replace the original extract table by renaming the newly created table. Optionally, you can create a backup of the original table before replacing it.

A sample SQL workflow is provided below. Customize the components marked in blue, while the remaining parts of the query are standard.

  1. Create a temporary table (database_name.new_table_name) that supports altering.

    create table database_name.cdv_table_name_new (table_definition) partitioned by (partition_field string) tblproperties('transactional'='false');

  2. Copy existing data from the original extract target.

    insert into database_name.cdv_table_name_new partition(partition_field) select * from database_name.cdv_table_name;

  3. [Optional] Save the original extract target as a backup.

    alter table database_name.cdv_table_name rename to database_name.cdv_table_name_bak;

  4. Make the temporary table the current extract target.

    alter table database_name.cdv_table_name_new rename to database_name.cdv_table_name;
