Question

Hive creates an iceberg table and inserts data, but the data is in a temporary table and cannot be found in the created table. How does the data need to be migrated

I would guess that you are using Hive 3.1.x, and using Tez execution engine.

Either use Hive 4.0.0 (with the embedded Iceberg), or use Hive 3.1.x with MR for write, and Tez for read.
See the supported configurations on https://iceberg.apache.org/docs/latest/hive/#feature-support

Hello, I am using hive in CDH, version 2.1.1. Does it not support iceberg?? Writing data is in the temporary table, and data migration is not feasible. It has been in the temporary table for a long time

In this case you should ask your vendor. A year ago, CDH did not support Iceberg tables.
