URL: https://github.com/apache/iceberg/issues/10286
### Apache Iceberg version
1.4.3
### Query engine
Hive
### Please describe the bug 🐞
In the iceberg documentation it could be seen that
"To enable Hive support globally for an application, set
iceberg.engine.hive.enabled=true in its Hadoop configuration."
The value of iceberg.engine.hive.enabled must be true in order to enable
hive support. However, it could still use Iceberg's hive support even if it is
set as "iceberg.engine.hive.enabled" to false. If i understand correctly, the
value "iceberg.engine.hive.enabled" is irrelevant.
Current scenario:
if it is a hive catalog we are setting engine.hive.enabled as true.
In
[iceberg/hive-metastore/src/main/java/org/apache/iceberg/hive/HiveTableOperations.java](https://github.com/apache/iceberg/blob/01bc864b8eb8c4ca4240af85f00f4e67c78c466e/hive-metastore/src/main/java/org/apache/iceberg/hive/HiveTableOperations.java#L486)
Line 486 in
[01bc864](https://github.com/apache/iceberg/commit/01bc864b8eb8c4ca4240af85f00f4e67c78c466e)
Even when we set ConfigProperties.ENGINE_HIVE_ENABLED to FALSE in Hadoop
configuration, we are passing the ConfigProperties.ENGINE_HIVE_ENABLED as TRUE
in the HiveIcebergMetaHook#commitCreateTable if it's of HiveCatalog type.
We are initially evaluating the 'engine.hive.enabled' value in
HiveTableOperations#hiveEngineEnabled. In cases where it's a Hive catalog, this
value is consistently 'True', rendering the 'iceberg.engine.hive.enabled' as
unnecessary.
