Description

Our internal tool found HADOOP-15523 breaks public API compatibility:

class CommonConfigurationKeysPublic

	Change	Effect
1	Field HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_SECS has been renamed to HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_KEY.	Recompilation of a client program may be terminated with the message: cannot find variable HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_SECS in CommonConfigurationKeysPublic.
2	Field HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_SECS_DEFAULT has been renamed to HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_DEFAULT.	Recompilation of a client program may be terminated with the message: cannot find variable HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_SECS_DEFAULT in CommonConfigurationKeysPublic.

HADOOP_SECURITY_GROUP_SHELL_COMMAND_TIMEOUT_SECS_DEFAULT is used to instantiate a variable in ShellBasedGroupsMapping objects, and since almost all applications requires groups mapping, this can cause runtime error if application loads multiple versions of Hadoop library.

IMO this is a blocker for 3.2.0
