Description

Token renewal/cancelation in the RM presents challenges to support arbitrary tokens. The RM's CLASSPATH is currently required to have token renewer classes and all associated classes for the project's client. The logistics of having installs on the RM of all hadoop projects that submit jobs - just to support client connections to renew/cancel tokens - are untenable.
