David Morávek commented on FLINK-25224:
---------------------------------------
Good catch [~chesnay].
{code}
<!--
Hive 2.3.4 relies on Hadoop 2.7.2 and later versions.
For Hadoop 2.7, the minor Hadoop version supported for
flink-shaded-hadoop-2-uber is 2.7.5
-->
<hivemetastore.hadoop.version>2.7.5</hivemetastore.hadoop.version>
{code}
I think we might be able to simplify this and get rid of the extra
`hadoop.version` for hive as this should solve the compatibility issues. I'll
open a PR for that.

> 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.
