   > How does it affect hadoop classpath? As far as I know, many downstream 
projects require adding the output of hadoop classpath to their classpath.
   
   * does nothing for maven/gradle imports of hadoop-cloud-storage
   * if you add hadoop/common/* and hadoop/commmon/lib/* to your CP you may now 
get more cloud connectors
   
   > I suppose it has no effect on hadoop-client-* jars, right?
   
   correct
   
   > Which maven profiles will be enabled by the Apache binary release? in 
other words, how to reproduce it from the source release locally?
   
   It doesn't set any of the new profiles, meaning the hadoop-* jars will be 
there, abfs will work (limited dependendencies) but anything else needs extra 
jars added. 
   
   FWIW third-party cloud deployments (EMR, azure etc) all get their connectors 
onto the classpath, somehow. And because hadoop-aws has a bit of bash script in 
its src/main, somehow it gets into "bin/hadoop fs" commands...the shell script 
wiring up logic does this.
