impala java api 操作_Cloudera Manager API操作Yarn/Impala队列资源

可以使用 Cloudera Manager API 操作 Yarn/Impala 队列资源，以下是一些操作的示例：

1. 获取 Yarn 队列信息：

GET /api/v19/clusters/<clusterName>/services/yarn/yarnScheduler

2. 获取 Impala 队列信息：

GET /api/v19/clusters/<clusterName>/services/impala/impalaConfiguration

3. 设置 Impala 队列资源限制：

PUT /api/v19/clusters/<clusterName>/services/impala/impalaConfiguration

{
  "items": [
    {
      "name": "impala_scheduler_allocation_file",
      "value": "/etc/hadoop/conf/impala_scheduler_allocation.xml"
    },
    {
      "name": "impala_max_concurrent_queries",
      "value": "50"
    },
    {
      "name": "impala_max_queued_queries",
      "value": "100"
    }
  ]
}

这些操作可以通过编写 Java 代码来实现 Impala Java API 操作。
