 docker containerizer fails when container exits quickly
 ---

 Key: MESOS-1726
 URL: https://issues.apache.org/jira/browse/MESOS-1726
 Project: Mesos
  Issue Type: Bug
  Components: containerization
Reporter: Jay Buffington
Assignee: Timothy Chen
  Labels: docker

 There is a race condition in the docker containerizer code that can usually 
 be reproduced by running a command that exits quickly (for example, true) 
 inside of a docker container.  You will see the error Unable to get executor 
 pid after launch” in the logs and the master will get a {{TASK_LOST}}.
 This race is between docker inspect” and the process running inside the 
 container.  When the processes inside the container exits (successful or not) 
 before docker inspect runs docker inspect will return a Pid of 0.  When the 
 pid is zero the {{Docker::Container::create}} method will set the pid to an 
 empty {{Optionpid_t}}.  This will cause the {{launch}} method to return 
 a {{Failure()}}.

When you attempt to start slave or master and there's another one already 
running there, it is nice to report what are the actual parameters to {{bind}} 
call that failed.

I saw that as well. That's after we turned on the glog signal handler for our 
tests.

It appears that we receive a SIGPIPE when we try to shutdown the zk test 
server. This happens for other zk tests as well. Only happens on Mac.

I am wildly guessing here, without proper testing... 
Could we possibly have hit an upstream issue in Zookeeper due to their usage of 
MSG_NOSIGNAL, which isn't functional on OSX (see [this lesson 
learned|https://issues.apache.org/jira/browse/MESOS-912?focusedCommentId=13899069page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13899069]

 socket errors should show IP address
 

 Key: MESOS-1661
 URL: https://issues.apache.org/jira/browse/MESOS-1661
 Project: Mesos
  Issue Type: Task
  Components: libprocess
Reporter: David Robinson
Assignee: Ken Sipe
Priority: Minor
  Labels: newbie

 [Log messages that show socket 
 errors|https://github.com/apache/mesos/blob/master/3rdparty/libprocess/src/process.cpp#L1035]
  (Connection refused, Broken pipe etc) should also show the remote IP 
 address. It's difficult to troubleshoot why a connection is being refused 
 when you don't know where it's trying to connect.

$ clang --version
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.3.0
Thread model: posix

Relevant output from `make check`:
