Creating an Iceberg table

A step-by-step procedure describes how to create an Apache Iceberg table from a client connection to Hive or Impala, or from Hue in Cloudera Data Hub. You see how to access and use the query editor Hue to create an Iceberg table.

In this task, from a Data Hub cluster, you open Hue, and use Hive or Impala to create a table.

You must meet the prerequisites to query Iceberg tables, including obtaining Ranger access permissions.

Log into Cloudera, and click Data Hub Clusters.
Click Hue.
Select a database.
Enter a query to create a simple Iceberg table in the default Parquet format.
Hive example:
```
CREATE EXTERNAL TABLE ice_t1 (i int, s string, ts timestamp, d date)
STORED BY ICEBERG;
```
Impala example:
```
CREATE TABLE ice_t2 (i int, s string, ts timestamp, d date)
STORED BY ICEBERG;
```
In Cloudera, CREATE EXTERNAL TABLE, and just CREATE TABLE, are valid from Hive. You use the EXTERNAL keyword from Hive to create the Iceberg table to purge the data when you drop the table. In Cloudera, from Impala, you must use CREATE TABLE to initialize the Iceberg table.
Click to run the query.
