[droberts-yb]

When running tpccbenchmark with log4j enabled, the process crashes with. FATAL error, when a node failure occurs:
When logging is not enabled, tpccbenchmark continues running when a node failure occurs.

The build is the latest main branch from the git repo (as of 6th April 2023).

Log Configuration
The only line I changed in the log4j.properties file is this one:
log4j.logger.com.oltpbenchmark.api=DEBUG

Environment
3 node Universe with RF3 in AWS.
Each node is 8vcpu

Steps To Reproduce

1. Edit the log4j.properties as above.
2. Run the standard create, load steps of the tpccbenchmark tool to build a 100 warehouse tpcc test database.
3. Start the execute phase of the tpccbenchmark tool and check its generating the log. It should include lines like:

17:14:04,832 (Worker.java:563) DEBUG - Worker<975> Delivery/04 Result: SUCCESS
17:14:04,857 (Worker.java:563) DEBUG - Worker<935> NewOrder/01 Result: SUCCESS
17:14:04,875 (Worker.java:563) DEBUG - Worker<506> Payment/02 Result: SUCCESS

4. Stop a node via the AWS admin console
   The error occurs the instant the node is shutdown.

5. Restart the node that was shutdown and let it rejoin the cluster

6. Restart the execute phase of the tpccbenchmark tool and check its producing the logs as above

7. Stop a node via the AWS admin console
   The error occurs the instant the node is shutdown.

Background
The log output as per above is required to feed into a utility that visualises what tpcc transaction type each worker is doing is in real-time.
The purpose is to visually show that the database continues running when a node fails and clients stay running.
