fengguangyuan opened a new issue #3336:
URL: https://github.com/apache/iceberg/issues/3336
# What's the problem?
In our practices of overwriting partitions with HiveCatalog, we have more
than `CLIENT_POOL_SIZE_DEFAULT` threads running on `ClientPool`, no doubts the
committing snapshot thread may waiting on the client pool, in which it is
possible to lead to hive table lock leak, if it's interrupted at this moment.
In such case, we need to have the bests efforts to release the lock.
# Affected code?
``HiveTableOperations.java`
```java
@VisibleForTesting
void doUnlock(long lockId) throws TException, InterruptedException {
released = metaClients.run(client -> {
client.unlock(lockId);
return null;
});
}
```
# How to re-produce?
Have more than `CLIENT_POOL_SIZE_DEFAULT` threads to do commit, and make the
threads interrupted.
