 <div class="block">RAS scheduler will try to distribute ackers evenly over workers by adding some ackers to each newly launched worker.
  Validations are performed here:
  (<a href="../Config.html#TOPOLOGY_RAS_ACKER_EXECUTORS_PER_WORKER"><code>Config.TOPOLOGY_RAS_ACKER_EXECUTORS_PER_WORKER</code></a> * memory for an acker
       + memory for the biggest topo executor) &lt; max worker heap memory.
     When RAS tries to schedule an executor to a new worker,
     it will put <a href="../Config.html#TOPOLOGY_RAS_ACKER_EXECUTORS_PER_WORKER"><code>Config.TOPOLOGY_RAS_ACKER_EXECUTORS_PER_WORKER</code></a> ackers into the worker first.
     So <a href="../Config.html#TOPOLOGY_WORKER_MAX_HEAP_SIZE_MB"><code>Config.TOPOLOGY_WORKER_MAX_HEAP_SIZE_MB</code></a> need to be able to accommodate this.</div>
