Till Rohrmann commented on FLINK-7284:
--------------------------------------
I think we have to use something similar to the {{git-commit-id-plugin}} which
allows us to store build information in the generated jar. Not sure if
something like that exists. I think we have to make some research there.
> Verify compile time and runtime version of Hadoop

> 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.
