Project: Hadoop YARN
Issue Type: Bug

Since we are calling {{setDiagnosticsMessage}} in {{nodeHeartbeat}}, which
can be called concurrently, the static {{resync}} and {{shutdown}} may have
wrong diagnostics messages in some cases.
On the other side, these static members can hardly save any memory, since the
normal heartbeat responses are created for each heartbeat.

Thanks [~chengbing.liu] for the patch.
bq. Since we are calling setDiagnosticsMessage in nodeHeartbeat, which can be
called concurrently, the static resync and shutdown may have wrong diagnostics
messages in some cases.
I see diagnostics message is setting into resync/shutdown response objects
before returning them. Can you give more details about a case where race
condition could occur?
bq. these static members can hardly save any memory, since the normal heartbeat
responses are created for each heartbeat.
I agree on this.

Chengbing Liu commented on YARN-3826:
-
[~devaraj.k], is it possible that two heartbeats happen at the same time?
Because the following code
{code}
shutDown.setDiagnosticsMessage(message);
return shutDown;
{code}
is not atomic, race can happen when two threads run to this point
simultaneously.

Race condition in ResourceTrackerService: potential wrong diagnostics messages
--
Key: YARN-3826
URL: https://issues.apache.org/jira/browse/YARN-3826
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: Chengbing Liu
Assignee: Chengbing Liu
Attachments: YARN-3826.01.patch
Since we are calling {{setDiagnosticsMessage}} in {{nodeHeartbeat}}, which
can be called concurrently, the static {{resync}} and {{shutdown}} may have
wrong diagnostics messages in some cases.
On the other side, these static members can hardly save any memory, since the
normal heartbeat responses are created for each heartbeat.
