> 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
