----------------------------------
Summary: Add default implementations to all Isolator virtual
functions
Key: MESOS-5435
URL: https://issues.apache.org/jira/browse/MESOS-5435
Project: Mesos
Issue Type: Improvement
Reporter: Kevin Klues
Currently, all of the virtual functions in `mesos::slave::Isolator` are pure
virtual (expect status()). For many isolators, however, it doesn't make sense
to implement all of these virtual functions. Each isolator has to provide its
own default implementation of these functions even if they aren't really
relying on them. This adds unnecessary extra code to many isolators that don't
need them.
Moreover, the `MesosIsolatorProcess` has the same problem for each of its
virtual functions.
We should provide defaults for these instead of making each and every isolator
implement even in cases when it doesn't make sense.
