Naganarasimha G R commented on YARN-4596:
-----------------------------------------
Hi [~gtCarrera] IIUC you are referring to
{{org.apache.hadoop.yarn.client.api.impl.TimelineWriter.doPosting(Object,
String)}}
{code}
if (resp == null ||
resp.getClientResponseStatus() != ClientResponse.Status.OK){
...
}
{code}
we need to check if resp Obj is available (not null) and if so then we need to
try to get {{resp.getEntity(TimelinePutResponse.class)}} and may be have a
proper *toString* overrides to log the errors rights?
> SystemMetricPublisher should not swallow error messages from
> TimelineClient#putEntities
