-----------------------------------------
Summary: Detecting whether executor is generated for command task
should work when the launcher_dir changes
Key: MESOS-10084
URL: https://issues.apache.org/jira/browse/MESOS-10084
Project: Mesos
Issue Type: Bug
Reporter: Andrei Sekretenko
As currently implemented, on recovery Mesos agent determines that the executor
is generated for command task by comparing the executor command with a current
path to Mesos executor:
https://github.com/apache/mesos/blob/1.7.x/src/slave/slave.cpp#L9635
During upgrade of production cluster we observed this check to break due to the
new launcher_dir being different from the one of checkpointed executor.
This can cause problems of various kind: for example, after such upgrade, Mesos
master can begin to treat the checkpointed command executors as subject to
resource quota.
