Thanks a lot @arunsarin85 for the patch. My concern is that this is a real production issue and by changing the test we are masking the problem.

…mapper reprocess to single worker
What changes were proposed in this pull request?
This pull request is to reduce intermittent failures in org.apache.hadoop.ozone.recon.api.TestContainerEndpoint by making container key mapper reprocess use a single iterator thread and single worker in the test’s OzoneConfiguration (ReconServerConfigKeys.OZONE_RECON_TASK_REPROCESS_MAX_ITERATORS and OZONE_RECON_TASK_REPROCESS_MAX_WORKERS set to 1 in setUp()).
To fix the issues with wrong key counts and API assertions, I restricted how many tasks run at once during the ContainerKeyMapper reprocess. It’s still running in parallel to mirror production just with more stability
