David Morávek updated FLINK-25224:
----------------------------------
Description:
In order to leverage new Hadoop features without reflection based workaround,
we want to bump the minimum supported version of Hadoop to 2.8.5 (released in
2018). There were no reported objections from the community against dropping
support for older versions.
Please note that this doesn't break the binary protocol compatibility, which
means that 2.8.5 client can still talk to older servers.
Discussion thread:

was:Now the Hadoop version of Flink is 2.4.1, but mostly the flink runtime
env classpath has higher Hadoop version. It means when we want to use some
feature in the higher version Hadoop, we need to use reflection which is so
hard to maintain.
