By default, hive.support.concurrency is true and DummyTxnManager requires a ZooKeeper quorum.

how about adding configurations to make ZooKeeperHiveLockManager work? I suppose it does not have deadlock issue like the DBTxManager?

Sounds reasonable

ZooKeeperHiveLockManager implements Table lock by persistent ZNode. It shall have the same problem.

EmbeddedLockManager is a better choice. It stores locks in memory.
