[jira] [Commented] (MESOS-3738) Mesos health check is invoked
incorrectly when Mesos slave is within the docker container
[ https://issues.apache.org/jira/browse/MESOS-3738?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14958274#comment-14958274 ]
Yong Tang commented on MESOS-3738:
----------------------------------
Tried to pass environmental variable MESOS_LAUNCHER_DIR with
sudo docker run -e MESOS_LAUNCHER_DIR=q/usr/libexec/mesos ...
but got the same result.
It seems that in mesos/src/docker/executor.cpp Ln 573-576:
const Option<string> envPath = os::getenv("MESOS_LAUNCHER_DIR");
string path =
envPath.isSome() ? envPath.get()
: os::realpath(Path(argv[0]).dirname()).get();
The environmental variable MESOS_LAUNCHER_DIR is not passed and argv[0] is used (which is the sandbox directory, not the launcher directory) for health check directory.
