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

> || ||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
