Ability to specify Hadoop version in Maven

[Giuseppe Valente]

Hi,

I have a project that has a dependency on hbase-mapreduce (2.4.9), which in 
turn depends on hbase-hadoop2-compat. The latter doesn’t have any version 
specified for hadoop-mapreduce-client-core and ends up pulling 2.10.0, which 
conflicts with the Hadoop version I’m running against (3.3.1). What’s the 
correct way to force hadoop-mapreduce to work with Hadoop 3.3.1? I tried using 
profiles but I couldn’t get it to work, I wonder if it has anything to do with 
this change <https://issues.apache.org/jira/browse/HBASE-24309>:
