Question

当我调用REST API方法/{cluster_id}/nodes

时

某些节点返回包含完整信息，而其他节点则不包含。例如，此节点返回info：

"node_ip": "10.20.155.122",
"network_interfaces": [
  "lo",
  "em1",
  "em2",
  "em3",
  "em4",
  "bond0",
  "bond1"
],
"ec2": {
  "instance-type": null,
  "placement": null,
  "ami-id": null,
  "instance-id": null
},
"node_version": {
  "search": null,
  "jobtracker": null,
  "tasktracker": null,
  "spark": {
    "master": false,
    "version": "1.1.0.2",
    "worker": true
  },
  "dse": "4.6.0",
  "cassandra": "2.0.11.83"
},
"dc": "Analytics",
"node_name": "BG1322",
"num_procs": 32,
"streaming": {

},
"token": "-1269200298813728863",
"data_held": 34651894.0,
"mode": "normal",
"rpc_ip": "10.20.155.122",
"partitions": {
  "saved_caches": "/dev/mapper/BG1322_applvol",
  "commitlog": "/dev/mapper/BG1322_applvol",
  "other": 
............ 
etc

这个没有（node_name，data_held）：

"node_ip": "10.20.155.123",
"network_interfaces": null,
"ec2": {

},
"node_version": {

},
"dc": "Analytics",
"node_name": null,
"num_procs": null,
"streaming": {

},
"token": "-4096905490099169213",
"data_held": null,
"mode": "unknown",
"rpc_ip": "10.20.155.123",
"partitions": {
  "saved_caches": null,
  "commitlog": null,
  "other": null,
  "data": null
},
"os": null,
"rack": "rack1",
"last_seen": 0

}， { “load”：null， “has_jna”：false， “vnodes”：是的， “设备”： { “saved_caches”：null， “commitlog”：null， “其他”：null， “data”：null }， “task_progress”：{

},

为什么会出现这种情况的任何想法？

为什么Datastax OpsCentre无法读取群集中某些节点的节点信息？
