Yarn作為一款優秀的開源叢集管理工具，可以用它來運作Hadoop，Spark，Flink等大資料處理任務。所有的分布式計算架構，都是主從模式，ResourceManager作為叢集的管理者，是任務送出的入口。一般企業的大資料處理平台會在Yarn的基礎中做進一步的封裝，以web應用的形式提供更進階的大資料處理平台。如果web應用通過shell的方式送出任務将顯得太重，而且不利于任務狀态的監控。幸好Yarn提供了ResourceManager的REST API，可以很友善的向叢集送出、殺死任務或者監控任務的狀态，本文将簡要介紹ResourceManager REST API的使用方法。
向叢集送出任務
先通過POST請求生成application_id再通過這個id來送出任務。
生成application-id
通過POST請求rm-http-address:port/ws/v1/cluster/apps/new-application，不需要參數，ResourceManager将傳回application_id與叢集可用資源配額，如下：
請求url
http://cdh-1:8088/ws/v1/cluster/apps/new-application 請求參數：無

| maximum-resource-capability | object | The maximum resource capabilities available on this cluster |
maximum-resource-capability元素說明
| memory | int | 容器可用的最大記憶體 |
| vCores | 容器可用的最大核心數 |
送出任務
送出應用程式API可用于送出應用程式。如果送出申請，則必須首先使用
Cluster New Application API獲得一個應用程式ID 。應用程式ID必須是請求正文的一部分。響應包含指向應用程式頁面的URL，可用于跟蹤應用程式的狀态和進度。

傳回資料： 無
送出後ResourceManager不會傳回資訊。從請求的參數可以看出，如果想通過Yarn來管理某個分布式計算任務，必須有對應的ApplicationMaser實作，如上例中的AppMaster.jar，其執行入口類為org.apache.hadoop.yarn.applications.distributedshell.ApplicationMaster。常見的分布式計算任務如Hadoop、Spark與Flink都有，但Flink-yarn項目對Flink 1.9貌似還 沒有實作對應的ApplicationMaster，是以Flink 1.9的任務目前還不能通過Rest API送出（1.7可以）。
查詢任務狀态資訊
查詢所有任務
通過GET請求rm-http-address:port/ws/v1/cluster/apps将擷取到所有任務的資訊清單，如
http://cdh-:8088/ws/v1/cluster/apps 請求參數（可選）
可以為GET操作指定多個參數。開始時間和結束時間都有一個begin和end參數，以允許您指定範圍。例如，可以請求在2021年3月2日早上09:00:00和早上10:00：00之間啟動的所有應用程式，其中startedTimeBegin = 1614646800000＆startedTimeEnd = 1614650400000。如果未指定Begin參數，則預設為0；如果未指定End參數，則預設為無窮大。

} 傳回結果為
{

} 其實的state的狀态為目前程式的狀态【RUNNING, ACCEPTED】
重新通過GET請求該任務的狀态
發現該任務已經被kill了
{
"state":"KILLED"
} 檢視與調整任務優先級
主要通過通路rm-http-address:port/ws/v1/cluster/apps/{appid}/priority來完成。統一需要得到RM web services的授權
