Here is how to restart specific host components:
| Code Block |
|---|
curl -uadmin:admin -H 'X-Requested-By: ambari' -X POST -d '
{
"RequestInfo":{
"command":"RESTART",
"context":"Restart ZooKeeper Client and HDFS Client on c6401.ambari.apache.org",
"operation_level":{
"level":"HOST",
"cluster_name":"c1"
}
},
"Requests/resource_filters":[
{
"service_name":"ZOOKEEPER",
"component_name":"ZOOKEEPER_CLIENT",
"hosts":"c6401.ambari.apache.org"
},
{
"service_name":"HDFS",
"component_name":"HDFS_CLIENT",
"hosts":"c6401.ambari.apache.org"
}
]
}' http://localhost:8080/api/v1/clusters/c1/requests |
Note: When RESTART is applied to a CLIENT, it refreshes the configs.
