             Summary: Add mechanism for testing recovery of HTTP based executors
                 Key: MESOS-4255
                 URL: https://issues.apache.org/jira/browse/MESOS-4255
             Project: Mesos
          Issue Type: Bug
            Reporter: Anand Mazumdar


Currently, the slave process generates a process ID every time it is 
initialized via {{process::ID::generate}} function call. This is a problem for 
testing HTTP executors as it can't retry if there is a disconnection after an 
agent restart since the prefix is incremented. 

{code}
Agent PID before:
slave(1)@127.0.0.1:43915

Agent PID after restart:
slave(2)@127.0.0.1:43915

There are a couple of ways to fix this:
- Add a constructor to {{Slave}} exclusively for testing that passes on a fixed 
{{ID}} instead of relying on {{ID::generate}}.
- Currently we delegate to slave(1)@ i.e. (1) when nothing is specified as the 
URL in libprocess i.e. {{127.0.0.1:43915/api/v1/executor}} would delegate to 
{{slave(1)@127.0.0.1:43915/api/v1/executor}}. Instead of defaulting to (1), we 
can default to the last known active ID.
