Todd Lipcon commented on MAPREDUCE-2265:
----------------------------------------
bq. I don't want to include the platform name simply because then all of the
scripts need to consistently figure out the platform name
We already do this for the native libs, why is the task-controller any
different? Besides, the scripts never call the task-controller, only the TT
does, where the PlatformName class is readily available.
bq. For universal tar balls, I think that a post-untar setup script makes the
most sense
Then the tarball environment and the product of a build start looking rather
different, we have extra install complexity, etc.
bq. I guess you could also have different hadoop home directories in the
tarball with symlinks between them.
Building two entirely parallel HADOOP_HOMES for different architectures out of
a series of symlinks? That sounds like a disaster waiting to happen.
> 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.
