Description:
{code:title=https://github.com/apache/ozone/blob/a455597815a4a12ded9479f334780a83116a2123/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/replication/ReplicationSupervisor.java#L164-L165}
tpe.setMaximumPoolSize(threadCount);
tpe.setCorePoolSize(threadCount);
{code}
The above code works when increasing thread pool size, but fails when

java.util.concurrent.ThreadPoolExecutor.setMaximumPoolSize(ThreadPoolExecutor.java:1680)

org.apache.hadoop.ozone.container.replication.ReplicationSupervisor$Builder.lambda$build$1(ReplicationSupervisor.java:164)
at
org.apache.hadoop.ozone.container.replication.ReplicationSupervisor.nodeStateUpdated(ReplicationSupervisor.java:294)
{code}
Core pool size needs to be decreased first to satisfy preconditions.
