--------------------------------------
Summary: Update the allocator to handle hierarchical roles.
Key: MESOS-7024
URL: https://issues.apache.org/jira/browse/MESOS-7024
Project: Mesos
Issue Type: Task
Components: allocation
Reporter: Benjamin Mahler
With the addition of hierarchical roles, the allocator needs to be updated to
perform a tree traversal to perform fair sharing allocation.
The quota implementation will not be heavily impacted since, as discussed
above, we will only allocate based on role quota (the leaf nodes). The role
expression (non-leaf nodes, e.g. /foo/*) will have no impact on quota
allocation for now.
The allocator will expect roles to be specified in the new format, which means
the master will need to translate roles accordingly when communicating with the
allocator.
