Owen O'Malley commented on MAPREDUCE-2265:
------------------------------------------
But it is *only* useful for universal binary tarballs. For RPM's for instance,
you can just put the right one in to place and remove a unnecessary level of
indirection.
For the fat binary tarballs, how about if it looks like:
libexec/arch/$ARCH/*
libexec/task-controller is a symlink to one of the executables that are in the
arch folder?
> task-controller and jsvc should install into sbin/<platform>/ directory

> Key: MAPREDUCE-2265
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2265
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: build, task-controller, tasktracker
> Affects Versions: 0.22.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Blocker
> Fix For: 0.22.0
>
>
> Currently the task-controller and jsvc "live" in the bin/ directory
> regardless of build platform. This is incorrect since these components are
> native compiled code and thus are built for a particular architecture. So,
> when we ship a build of 22, we will want to ship both 32-bit and 64-bit
> artifacts so users can use these components without rebuilding on their own.
> Additionally, it doesn't make sense for them to be in bin/ since they're not
> user-facing in any way (i.e a user would never directly invoke them). So I
> would propose putting them in an sbin directory.
> The final proposed path is $HADOOP_HOME/sbin/<platform>/{jsvc,task-controller}
> Note this is not an incompatible change since these components were not
> present in any prior apache release.
