Examples of org.apache.hadoop.hbase.regionserver.snapshot.RegionServerSnapshotManager$SnapshotSubprocedurePool

org.apache.hadoop.hbase.regionserver.snapshot.RegionServerSnapshotManager
We use the SnapshotSubprocedurePool, a class specific thread pool instead of {@link org.apache.hadoop.hbase.executor.ExecutorService}. It uses a {@link java.util.concurrent.ExecutorCompletionService} which provides queuing ofcompleted tasks which lets us efficiently cancel pending tasks upon the earliest operation failures. HBase's ExecutorService (different from {@link java.util.concurrent.ExecutorService}) isn't really built for coordinated tasks where multiple threads as part of one larger task. In RS's the HBase Executor services are only used for open and close and not other threadpooled operations such as compactions and replication sinks.
