-------------------------------------
Hi, [~till.rohrmann] I would like work on this, but before start working. I
have some things need to confirm with you.
1. How can I get runtime version of hadoop ? I think
{{VersionInfo.getVersion()}} should be a correct way to get it.
2. How can I get compile time or called build time version of hadoop ? you said
it has to be included in the Flink binaries, hmm. I think I should confirm it.
I found there is a file called {{flink-conf.yaml}}. Do I need to add a key like
called {{hadoop.version}} in this file? and when loading configuration property
as cluster start up, then I can get this value.
3. After geting these two value, check x==y or x!=y.
4. Done.
Thanks, Minglei

> Key: FLINK-7284
> URL: https://issues.apache.org/jira/browse/FLINK-7284
> Project: Flink
> Issue Type: Improvement
> Components: Cluster Management
> Affects Versions: 1.4.0
> Reporter: Till Rohrmann
>
> In order to detect a potential version conflict when running a Flink cluster,
> built with Hadoop {{x}}, in an environment which provides Hadoop {{y}}, we
> should automatically check if {{x == y}}. If {{x != y}}, we should terminate
> with an appropriate error message. This behaviour should also be
> disengageable if one wants to run Flink explicitly in a different Hadoop
> environment.
> The check could be done at cluster start up using Hadoops {{VersionInfo}} and
> the build time Hadoop version info. The latter has to be included in the
> Flink binaries.
