---------------------------------
Summary: Allow master/agent to take multiple --modules flags
Key: MESOS-5173
URL: https://issues.apache.org/jira/browse/MESOS-5173
Project: Mesos
Issue Type: Task
Reporter: Kapil Arya
Fix For: 0.29.0
When loading multiple modules into master/agent, one has to merge all module
metadata (library name, module name, parameters, etc.) into a single json file
which is then passed on to the --modules flag. This quickly becomes cumbersome
especially if the modules are coming from different vendors/developers.
An alternate would be to allow multiple invocations of --modules flag that can
then be passed on to the module manager. That way, each flag corresponds to
just one module library and modules from that library.
Another approach is to create a new flag (e.g., --modules-dir) that contains a
path to a directory that would contain multiple json files. One can think of it
as an analogous to systemd units. The operator that drops a new file into this
directory and the file would automatically be picked up by the master/agent
module manager. Further, the naming scheme can also be inherited to prefix the
filename with an "NN_" to signify oad order.
