Issue when Querying YARN application information via REST API

Hi everybody,

I have a problem when querying the job info via the REST api. In the past, when I need to see the list of containers that are created for one specific job, I can query it like below and it shows me all the container information.

curl -XGET http://svr02.spo:8188/ws/v1/applicationhistory/apps/application_1445602639127_0365/appattempts/appattempt_1445602639127_0365_000001/containers
{"container":[
{
  "containerId":"container_e68_1445602639127_0365_01_000003",
  "allocatedMB":2048,
  "allocatedVCores":1,
  "assignedNodeId":"svr15.spo:45454",
  "priority":10,
  "startedTime":1446131587303,
  "finishedTime":1446131593180,
  "elapsedTime":5877,
  "diagnosticsInfo":"Container killed by the ApplicationMaster.\nContainer killed on request. Exit code is 143\nContainer exited with a non-zero exit code 143\n",
  "logUrl":"http://svr02.spo:8188/applicationhistory/logs/svr15.spo:45454/container_e68_1445602639127_0365_01_000003/container_e68_1445602639127_0365_01_000003/annemarie",
  "containerExitStatus":-105,
  "containerState":"COMPLETE",
  "nodeHttpAddress":"http://svr15.spo:8042"
},
{
  "containerId":"container_e68_1445602639127_0365_01_000002",
  "allocatedMB":2048,
  "allocatedVCores":1,
  "assignedNodeId":"svr12.spo:45454",
  "priority":20,
  "startedTime":1446131578209,
  "finishedTime":1446131586479,
  "elapsedTime":8270,
  "diagnosticsInfo":"Container killed by the ApplicationMaster.\nContainer killed on request. Exit code is 143\nContainer exited with a non-zero exit code 143\n",
  "logUrl":"http://svr02.spo:8188/applicationhistory/logs/svr12.spo:45454/container_e68_1445602639127_0365_01_000002/container_e68_1445602639127_0365_01_000002/annemarie",
  "containerExitStatus":-105,
  "containerState":"COMPLETE",
  "nodeHttpAddress":"http://svr12.spo:8042"
},
{
  "containerId":"container_e68_1445602639127_0365_01_000001",
  "allocatedMB":1024,
  "allocatedVCores":1,
  "assignedNodeId":"svr04.spo:45454",
  "priority":0,
  "startedTime":1446131572596,
  "finishedTime":1446131599631,
  "elapsedTime":27035,
  "diagnosticsInfo":"",
  "logUrl":"http://svr02.spo:8188/applicationhistory/logs/svr04.spo:45454/container_e68_1445602639127_0365_01_000001/container_e68_1445602639127_0365_01_000001/annemarie",
  "containerExitStatus":0,
  "containerState":"COMPLETE",
  "nodeHttpAddress":"http://svr04.spo:8042"
}]}

However, later, when I use the same query, the response only displays the information of ONE and ONLY ONE container: the application master. The other container information disappears mythically:

curl -XGET http://svr02.spo:8188/ws/v1/applicationhistory/apps/application_1445602639127_0365/appattempts/appattempt_1445602639127_0365_000001/containers
{"container":[
{
  "containerId":"container_e68_1445602639127_0365_01_000001",
  "allocatedMB":1024,
  "allocatedVCores":1,
  "assignedNodeId":"svr04.spo:45454",
  "priority":0,
  "startedTime":1446131572596,
  "finishedTime":1446131599631,
  "elapsedTime":27035,
  "diagnosticsInfo":"",
  "logUrl":"http://svr02.spo:8188/applicationhistory/logs/svr04.spo:45454/container_e68_1445602639127_0365_01_000001/container_e68_1445602639127_0365_01_000001/annemarie",
  "containerExitStatus":0,
  "containerState":"COMPLETE",
  "nodeHttpAddress":"http://svr04.spo:8042"
}
]
}

Does anyone have the same problem or experience this before? I really need to see the list of container information because I would like to query its starttime and endtime.

Thank you for your help!!

@Son Hai Ha

From this apache jira - https://issues.apache.org/jira/browse/YARN-3978, we can see that they have configuration option to turn off saving of non-AM container metadata. In order to have non-AM container details, we need to set "yarn.timeline-service.generic-application-history.save-non-am-container-meta-info" and "yarn.timeline-service.generic-application-history.enabled" to TRUE and restart RM and ATS.
