-----------------------------
Summary: The container logger should be responsible for making
sure stdout/stderr are writable by the task
Key: MESOS-6271
URL: https://issues.apache.org/jira/browse/MESOS-6271
Project: Mesos
Issue Type: Improvement
Affects Versions: 1.0.0
Reporter: Yan Xu
Today the container logger prepares the stdout/stderr for the executor but the
not the fetcher. The fetcher creates separate files (location hardcoded, with
O_TRUNC!) for its own stdout/stderr. The fetcher also does a recursive chown
(which has unintended side-effects and is being fixed in MESOS-5218) but it is
not even executed if the task doesn't fetch anything (e.g., with a command
executor). As a result by the time the executor needs to write to its
stdout/stderr, the files may belong to the task user or the agent user and its
by coincidence it doesn't fail more widely.
The fetcher should use the stderr/stdout prepared by the container logger and
the container logger should be responsible for making it writable by the task
user.
