jerryshao opened a new pull request #406: Throw an exception when using Iceberg with Spark embedded metastore URL: https://github.com/apache/incubator-iceberg/pull/406 Iceberg's hive catalog has two issues work with Spark embedded metastore: 1. Iceberg requires HIVE_LOCKS which doesn't exist in embedded metastore. 2. Embedded metastore restricts only one client at a time, so once Spark creates a client, then Iceberg cannot open a client anymore, vice versa. Here propose a simple fix to restrict users to use iceberg when embedded metastore is enabled.
