[jira] [Commented] (YARN-2879) Compatibility validation between YARN 2.2/2.4 and 2.6

    [ https://issues.apache.org/jira/browse/YARN-2879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14218388#comment-14218388 ] 

Zhijie Shen commented on YARN-2879:
-----------------------------------

a. In the following scenarios:

1. Either insecure or secure;
2. MR 2.2 with either old or new shuffle handler on NM;
3. Submitting via new client.

We will see the following console exception:

b. In the following scenarios:
1. Either insecure or secure;
2. MR 2.2 with old on NM;
3. Submitting via old client.

We will see the following exception in the AM Log:
{code}
2014-11-17 15:09:06,157 INFO [main] org.apache.hadoop.mapreduce.v2.app.MRAppMaster: Created MRAppMaster for application appattempt_1416264695865_0007_000001

{code}

The two exceptions are actually the same problem, but using the old client prevents it happening during app submission. Will file a separate Jira for it.

> Recently, I did some simple backward compatibility experiments. Bascially, I've taken the following 2 steps:
> 1. Deploy the application (MR and DistributedShell) that is compiled against *old* YARN API (2.2/2.4) on *new* YARN cluster (2.6). The application is submitted via *new* Hadoop (2.6) client.
> 2. Deploy the application (MR and DistributedShell) that is compiled against *old* YARN API (2.2/2.4) on *new* YARN cluster (2.6). The application is submitted via *old* Hadoop (2.2/2.4) client that comes with the app.
> I've tried these 2 steps on both insecure and secure cluster. Here's a short summary:
> || || || DS 2.2 || DS 2.4 || MR 2.2 + Shuffle 2.2 || MR 2.2 + Shuffle 2.6 || MR 2.4 + Shuffle 2.4 || MR 2.4 + Shuffle 2.6 ||
> | Insecure | New Client | OK | OK | Client Incompatible | Client Incompatible | OK | OK |
> | Insecure | Old Client | OK | OK | AM Incompatible | Client Incompatible | OK | OK |
> | secure | New Client | OK | OK | Client Incompatible | Client Incompatible | OK | OK |
> | secure | Old Client | OK | OK | AM Incompatible | Client Incompatible | OK | OK |
> Note that I've tried to run NM with both old and new shuffle handler version.
> In general, the compatibility looks good overall. There're a few issues that are related to MR, but they seem to be not the YARN issue. I'll post the individual problem in the follow-up comments.
