Ambari中的DataNode组件命令可以使用以下API:
1. 获取DataNode组件的状态:
```
GET /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
```
2. 启动DataNode组件:
```
PUT /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
{
"ServiceComponentInfo" : {
"state" : "STARTED"
}
}
```
3. 停止DataNode组件:
```
PUT /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
{
"ServiceComponentInfo" : {
"state" : "INSTALLED"
}
}
```
4. 重启DataNode组件:
```
PUT /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
{
"ServiceComponentInfo" : {
"state" : "INSTALLED"
}
}
PUT /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
{
"ServiceComponentInfo" : {
"state" : "STARTED"
}
}
```
5. 重新安装DataNode组件:
```
PUT /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
{
"ServiceComponentInfo" : {
"state" : "INIT"
}
}
PUT /api/v1/clusters/{clusterName}/services/HDFS/components/DATANODE
{
"ServiceComponentInfo" : {
"state" : "INSTALLED"
}
}
```
注意:需要替换{clusterName}为实际的集群名称。
