> It is observed that registering timeline v2 client with AMRMClient before serviceInit
throw exception in AppMaster. This causes AppMaster start up failure.
> {noformat}
> Caused by: org.apache.hadoop.yarn.exceptions.YarnException: register timeline v2 client
when not configured.
> 	at org.apache.hadoop.yarn.client.api.AMRMClient.registerTimelineV2Client(AMRMClient.java:708)
> 	at org.apache.hadoop.yarn.client.api.async.AMRMClientAsync.registerTimelineV2Client(AMRMClientAsync.java:354)
> {noformat}
> AMRMClient should not assume that timeline client will be registered only after serviceInit.
