How to tune Hadoop version in flink shaded jar to Hadoop version actually used?

[徐涛]

Hi Experts
        When running flink on YARN, from ClusterEntrypoint the system 
environment info is print out.
        One of the info is "Hadoop version: 2.4.1”, I think it is from the 
flink-shaded-hadoop2 jar. But actually the system Hadoop version is 2.7.2.
        I want to know is it OK if the version is different? Is it a best 
practice to adjust flink Hadoop version to the Hadoop version actually used?
        
        Thanks a lot.

Best
