> 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.
