Running compatibility checks with checkcompatibility.py

As an example, this invocation will check the compatibility of interfaces annotated as Public or LimitedPrivate:
./dev-support/bin/checkcompatibility.py --annotation org.apache.hadoop.classification.InterfaceAudience.Public --annotation org.apache.hadoop.classification.InterfaceAudience.LimitedPrivate --include "hadoop.*" branch-2.7.2 trunk

Changing the Hadoop version declared returned by VersionInfo
If for compatibility reasons the version of Hadoop has to be declared as a 2.x release in the information returned by
org.apache.hadoop.util.VersionInfo, set the property declared.hadoop.version to the desired version.
For example: mvn package -Pdist -Ddeclared.hadoop.version=2.11
If unset, the project version declared in the POM file is used.
