<p>看一下TaskManagerRunner的构造方法中</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpNeE5DOHpZVGhtT1RCaU1UWmlZemhqWkRnME1XVTROMlJqT1dOaE5HTXdNakE1WVM1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>调用了这个startTaskManager()方法，在这个方法中又调用了</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpjd09DODBOVE14WlRsa1lqZzRNamt3TlRReE9UVmhOVEEyWldaa05Ua3lOV0ZpWXk1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>在这个方法中.fromConfiguration()</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpVMU1pOWhNakpsTURNM05EVXdZelF5TnpNME1HSmxORFF4WW1Wall6WTBaREJqTUM1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>看到创建了一个networkEnevironment并且把它起了起来其中</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFM0wyVTRObVJoTldJME1UYzNOakUwTnpVMVlXWmlOVEJtTkdWak56TTJOVFV4TG5CdVp3PT0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>

<p>因为flink的网络是走的netty,可以看到它会初始化netty的客户端和服务端用于网络通信并且传入了bufferPool池,这个在以后随缘更新到 反压 会详细的研究</p>
<p>回到fromConfiguration()方法</p>
<p>network.start以后它又</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpVeU5TOHdPV0kwT0dFeU1tUTBOelEwTUdVeU9UZzJNMlV4WWpjM1pERTJNMk5tTlM1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>创建了内存管理类memoryManager和io管理类IOmanager, 这里以后随缘更新讲到内存和IO单独说</p>
<p>需要注意的是这里的Async异步IO,其实目前flink只有这一种异步的IO管理器</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpjM01DODBaRGhpWkdGa09HWmxNakUxTW1NeE1HRmlZV1JoT0RjNVlqYzNZekEyTWk1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>创建了定时器服务，定时器留到窗口在讲</p>
<p>回到startTaskManager()方法的最后</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFeE9TOW1NamM1WkRjMFlUWm1PV0kzTVdJeFlURTNOR00wWmpJeU1HTTRZVEF5Tnk1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>这个类TaskExecutor就是前面说的包含了RPC接口的类主要是实现了接口</p>
<p> <img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpJeE5pOWlaVFJrWWpneVl6QTFaVFpsTnpVNVpqUmxPVEppWkdVeE5qWmtNalkxTUM1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>里面包含了一些重要的方法的实现，来看一下有哪些重要的方法</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpFMU5TODRNVEkxWldFME1ERmpaV1kzTmpJME9EWXhNek5pWlRJd1pqRTVObVF3TXk1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>可以看到这是请求slot的</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpVeE55OW1PVE13TVdSbU5qTTBNV1F4TkRJellUWmxaVGsxT1dGbVkyWTBZV0poTlM1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>这是启动Task的其中这个tdd就包含了一些任务的信息上下游inputGate，resultPartition等 具体job启动的时候详细讲一下</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpRek1TOHdNbVl6TVRaa05XRmhPRGxoTmpKbE5qTmhPRE5rWVRZeVlXWmxOR0V4Tnk1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>这个方法也是比较重要的，可以看到这是一个触发checkPoint的RPC,这里可能会有疑问为什么Chenkpoint这个RPC会在TaskManager端</p>
<p>可以先简单的看下具体实现</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTl3YVdGdWMyaGxiaTVqYjIwdmFXMWhaMlZ6THpJek1TOHpaV05pWXpNME9XTmlPV1ExT0RjME16RmxOMk00TldOallUVm1ZMk0wTnk1d2JtYz0=" alt="Flink源码解读系列 | TaskManager启动" title="Flink源码解读系列 | TaskManager启动"></p>
<p>看到这里大致就知道了，其实这个RPC是留给Coordinator调用的，会触发生成Barrier的逻辑（也就是经常说的，coordinator会在source插入barriers用于分布式快照对齐）随缘更新到checkpoint的时候在细说吧</p>
<p>这里TaskManager就差不多启动起来了，当然TaskManager还有很多服务像HA,Heartbeat,BlobCache也会起起来，这里就不全部写出了。</p>
