-------------------------------
Summary: Docker containerizer should ignore pids of executors that
do not pass the connection check.
Key: MESOS-9672
URL: https://issues.apache.org/jira/browse/MESOS-9672
Project: Mesos
Issue Type: Improvement
Components: containerization
Reporter: Meng Zhu
When recovering executors with a tracked pid we first try to establish a
connection to its libprocess address to avoid reaping an irrelevant process:
https://github.com/apache/mesos/blob/4580834471fb3bc0b95e2b96e04a63d34faef724/src/slave/containerizer/docker.cpp#L1019-L1054
If the connection fails to establish, we should not track its pid:
https://github.com/apache/mesos/blob/4580834471fb3bc0b95e2b96e04a63d34faef724/src/slave/containerizer/docker.cpp#L1071
One trouble this might cause is that if the pid is being used by another
executor, this could lead to duplicate pid error and lead the agent into a
crash loop:
