Description

[meta comment: Total newcomer to mesos -- pardon what might be a trivial problem. (Meta-meta-comment: I couldn't find any pointers to forums or user groups where this might be more appropriately posted!)]

Short form: Working with a fresh and sandboxed build. When I start mesos-slave.sh, the master starts throwing [Errno 32] Broken pipe errors. Have I misconfigured something? What additional info should I gather?

Full synopsis:

Did:
===== build and test:
$ svn co https://svn.apache.org/repos/asf/incubator/mesos/trunk mesos-trunk
$ ./bootstrap
$ ./configure --prefix=$SANDBOX/usr --with-webui --with-included-zookeeper
$ make
$ make check
[==========] 172 tests from 33 test cases ran. (59027 ms total)
[ PASSED ] 172 tests.
$ # all looks good so far!
===== launch mesos-master:
$ bin/mesos-master.sh
