             Summary: HealthChecker launches helper binary each during health check attempt.
                 Key: MESOS-6766
                 URL: https://issues.apache.org/jira/browse/MESOS-6766
             Project: Mesos
          Issue Type: Improvement
    Affects Versions: 1.1.0, 1.2.0
            Reporter: Alexander Rukletsov


Currently the HealthChecker library launches a helper binary ({{curl}} for {{HTTP}}, {{mesos-tcp-connect}} for {{TCP}}, {{<user-command>}} for {{COMMAND}}) each time it attempts a health check. While it is unavoidable for {{COMMAND}} health checks, for {{HTTP}} and {{TCP}} we can do better. We probably can't send requests and try TCP handshakes directly from the library, i.e., executor process, because appropriate namespaces should be entered, but we can launch the binary only once and keep it running alongside the task process till the task is running.
