URL: https://github.com/apache/hive/pull/3365#issuecomment-1166051272
I was able to fix the tests.
The replication unit tests do not really allow updates to occur on the
replica, this because the two DbTxnHandlers (primary and replica) actually use
the same Derby database.
For the purposes of these tests, I can test the same (txnId skew) by doing
extra updates on the
primary to force the primary to have larger txnIds than the replica.

> REPL DUMP is replication all OpenXacts, even when they are from other non
> replicated databases. This wastes space in the dump, and ends up opening
> unneeded transactions during REPL LOAD.
>
> Add a config property for replication that filters out OpenXact events during
> REPL DUMP. During REPL LOAD, the txns can be implicitly opened when the
> ALLOC_WRITE_ID is processed. For CommitTxn and AbortTxn, dump only if WRITE
> ID was allocated.
