When I try to register my ApplicationMaster with YARN's RM, it fails.
In my ApplicationMaster's logs:

My registration code:
val appId = args(0).toInt
val attemptId = args(1).toInt
val timestamp = args(2).toLong
// these are our application master's parameters
val streamerClass = args(3)
val tasks = args(4).toInt
// TODO log params here
// start the application master helper
val conf = new Configuration
val applicationMasterHelper = new ApplicationMasterHelper(appId, attemptId,
timestamp, conf)
.registerWithResourceManager
.....
val rpc = YarnRPC.create(conf)
val appId = Records.newRecord(classOf[ApplicationId])
val appAttemptId = Records.newRecord(classOf[ApplicationAttemptId])
val rmAddress =
NetUtils.createSocketAddr(conf.get(YarnConfiguration.RM_ADDRESS,
YarnConfiguration.DEFAULT_RM_ADDRESS))
val resourceManager = rpc.getProxy(classOf[AMRMProtocol], rmAddress,
conf).asInstanceOf[AMRMProtocol]
var requestId = 0
appId.setClusterTimestamp(lTimestamp)
appId.setId(iAppId)
appAttemptId.setApplicationId(appId)
appAttemptId.setAttemptId(iAppAttemptId)
def registerWithResourceManager(): ApplicationMasterHelper = {
val req = Records.newRecord(classOf[RegisterApplicationMasterRequest])
req.setApplicationAttemptId(appAttemptId)
// TODO not sure why these are blank- This is how spark does it
req.setHost("")
req.setRpcPort(1)
req.setTrackingUrl("")
resourceManager.registerApplicationMaster(req)
this
}
My params are receiving the proper app/attempt/cluster timestamps:
app - 1
attempt - 1
timestamp - 1316556657998
