摘要：
随着大数据时代的到来，Hadoop YARN（Yet Another Resource Negotiator）作为Hadoop生态系统中的资源管理器，已经成为处理大规模数据集的重要工具。在YARN中，合理分配CPU核心数对于提高资源利用率、优化任务执行效率至关重要。本文将深入探讨YARN中应用级资源限制的CPU核心数分配策略，并给出相应的代码实现。
一、
Hadoop YARN是一个分布式资源管理系统，负责管理集群中的计算资源，并将这些资源分配给不同的应用程序。在YARN中，资源主要分为CPU、内存和磁盘I/O等。合理分配CPU资源，特别是CPU核心数，对于保证任务执行效率和资源利用率具有重要意义。
二、YARN资源分配机制
YARN的资源分配机制主要基于以下步骤：
1. 资源请求：应用程序向资源管理器（ResourceManager）请求资源。
2. 资源分配：资源管理器根据集群资源状况和应用程序需求，将资源分配给应用程序。
3. 资源监控：资源管理器监控应用程序的资源使用情况，并根据需要调整资源分配。
4. 资源回收：当应用程序完成或被终止时，资源管理器回收资源。
三、应用级资源限制：CPU核心数分配策略
在YARN中，应用级资源限制是指对单个应用程序的资源使用进行限制。对于CPU核心数，以下是一些常见的分配策略：
1. 固定核心数：为每个应用程序分配固定的CPU核心数。
2. 动态核心数：根据应用程序的实际需求动态调整CPU核心数。
3. 按需分配：根据应用程序的负载情况，按需分配CPU核心数。
四、代码实现
以下是一个简单的YARN应用程序，演示如何通过设置CPU核心数来实现应用级资源限制。
