| <td><h5>cluster.evenly-spread-out-slots</h5></td> |
| <td style="word-wrap: break-word;">false</td> |

| <td style="word-wrap: break-word;">(none)</td> |
| <td>Integer</td> |
| <td>The size of the IO executor pool used by the cluster to execute blocking IO operations (Master as well as TaskManager processes). By default it will use 4 * the number of CPU cores (hardware contexts) that the cluster process has access to. Increasing the pool size allows to run more IO operations concurrently.</td> |

| <td>Boolean</td> |
| <td>Whether processes should halt on fatal errors instead of performing a graceful shutdown. In some environments (e.g. Java 8 with the G1 garbage collector), a regular graceful shutdown can lead to a JVM deadlock. See <a href="https://issues.apache.org/jira/browse/FLINK-16510">FLINK-16510</a> for details.</td> |
