Alexander Rukletsov updated MESOS-1871: --------------------------------------- Assignee: (was: Alexander Rukletsov) > Sending SIGTERM to a task command may render it orphaned > -------------------------------------------------------- > > Key: MESOS-1871 > URL: https://issues.apache.org/jira/browse/MESOS-1871 > Project: Mesos > Issue Type: Bug > Components: slave > Reporter: Alexander Rukletsov > > {{CommandExecutor}} launches tasks wrapping them into {{sh -c}}. That means > signals are sent to the top process—that is {{sh -c}}—and not to the task > directly. Though {{SIGTERM}} is propagated by {{sh -c}} down the process > tree, if the task is unresponsive to {{SIGTERM}}, {{sh -c}} terminates > reporting success to the {{CommandExecutor}}, rendering the task detached > from the parent process and still running. Because the {{CommandExecutor}} > thinks the command terminated normally, its OS process exits normally and may > not trigger containerizer's escalation which destroys cgroups. > Here is the test related to the first part: > [https://gist.github.com/rukletsov/68259dfb02421813f9e6]. > Here is the test related to the second part: > [https://gist.github.com/rukletsov/3f19ecc7389fa51e65c0]. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
