Benjamin Mahler closed MESOS-448.
---------------------------------

    Resolution: Won't Fix

Closing as the Hadoop framework has been moved to github: https://github.com/mesos/hadoop

>                 Key: MESOS-448
>                 URL: https://issues.apache.org/jira/browse/MESOS-448
>             Project: Mesos
>          Issue Type: Bug
>            Reporter: Benjamin Mahler
>            Assignee: Benjamin Hindman
>            Priority: Critical
>
> This was broken by: https://reviews.apache.org/r/10581 (which I think was benh's change originally).
> Currently all TaskTrackers fail to launch with the following:
> Failed to determine the canonical path of mesos-launcher: No such file or directory
> I augmented the logging with the following in process_isolator.cpp:
>     // Determine path for mesos-launcher.
>     Try<string> realpath = os::realpath(
>         path::join(flags.launcher_dir, "mesos-launcher"));
>     if (realpath.isError()) {
>       EXIT(1) << "Failed to determine the canonical path of '"
>               << path::join(flags.launcher_dir, "mesos-launcher")
>               << "': " << realpath.error();
>     }
> Which now gets me the launcher path it's looking at:
> "Failed to determine the canonical path of '/usr/local/libexec/mesos/mesos-launcher': No such file or directory"
> Are we expecting a make install for this to work? Shouldn't this be working out of the build directory when no make install has taken place?
> On my system, I only have:
> $ sudo find / -name "mesos-launcher"
> /Users/bmahler/git/mesos/build/src/.libs/mesos-launcher
> /Users/bmahler/git/mesos/build/src/mesos-launcher
> /Users/bmahler/git/mesos3/build/src/.libs/mesos-launcher
> /Users/bmahler/git/mesos3/build/src/mesos-launcher
> /usr/local.old/libexec/mesos/mesos-launcher  // Possibly leftover from a OSX upgrade..
> The launcher directory is set from this flag:
>     add(&Flags::launcher_dir, // TODO(benh): This needs a better name.
>         "launcher_dir",
>         "Location of Mesos binaries",
>         MESOS_LIBEXECDIR);
> And in the Makefile.am:
> MESOS_CPPFLAGS += -DMESOS_LIBEXECDIR=\"$(pkglibexecdir)\"
> Looking at killtree() in process_utils.hpp, do we want to do something similar for the launcher?
>   if (os::hasenv("MESOS_KILLTREE")) {
>     // Set by mesos-build-env.sh.
>     cmdline = os::getenv("MESOS_KILLTREE");
>   } else if (os::hasenv("MESOS_SOURCE_DIR")) {
>     // Set by test harness for external tests.
>     cmdline = os::getenv("MESOS_SOURCE_DIR") +
>       "/src/scripts/killtree.sh";
>   } else {
>     cmdline = MESOS_LIBEXECDIR "/killtree.sh";
>   }
