> We faced similar issues: > > 1. We are using Flink and some processes attempt to modify a table concurrently, e.g.: ingestion process and data compaction process. If one of them fails then a lock can remain in `ACQUIRED` state. We clear all the logs from another process in `onInit` function. This is problematic. You should not `clear` locks. You should only do this when you are sure that the other process is not writing/committing. > 2. This one is weird. We see a lot of errors in logs: `Base metadata location '%s' is not same as the current table metadata location '%s' for %s.%s` [see](https://github.com/apache/iceberg/blob/6b8f7e0e31a81029b478e7757aba749f5ed27f42/hive-metastore/src/main/java/org/apache/iceberg/hive/HiveTableOperations.java#L295), which means table has been updated regardless of an acquired lock. This is exactly the case which could happen when the locks are removed during a commit and another process is trying to commit concurrenly. The correct solution for the issue is to try to make sure that the lock is removed by the failing process -- This is an automated message from the Apache Git Service.
