## Hadoop configuration
+### HadoopTables Lock Configuration
+
+When using `HadoopTables` (tables without a catalog), a `LockManager` can be
configured to ensure atomic commits on file systems like S3 that lack native
write mutual exclusion. Lock properties must be prefixed with
`iceberg.tables.hadoop.`.
+
+| Property | Default | Description
|
+| ------------------------------------------- | --------------- |
------------------------------------------------------ |
+| iceberg.tables.hadoop.lock-impl | null | a custom
implementation of the lock manager (e.g.,
`org.apache.iceberg.aws.dynamodb.DynamoDbLockManager`) |
+| iceberg.tables.hadoop.lock.table | null | an auxiliary
table for locking (e.g., DynamoDB table name) |
+| iceberg.tables.hadoop.lock.acquire-interval-ms | 5000 (5 s) | the interval
to wait between each attempt to acquire a lock |
+| iceberg.tables.hadoop.lock.acquire-timeout-ms | 180000 (3 min) | the
maximum time to try acquiring a lock |
+| iceberg.tables.hadoop.lock.heartbeat-interval-ms | 3000 (3 s) | the interval
to wait between each heartbeat after acquiring a lock |
+| iceberg.tables.hadoop.lock.heartbeat-timeout-ms | 15000 (15 s) | the
maximum time without a heartbeat to consider a lock expired |
Review Comment:
Thanks for the feedback! Updated to remove the duplicate table and instead
link to the existing Lock catalog properties section.
Here's the updated local rendering:
