Till Rohrmann created FLINK-7284:
------------------------------------
Summary: 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.
