Yan Xu commented on MESOS-6074:
-------------------------------
The problem seems to be that: since 1.0 we introduced a few gauges including
this one that depend on the sorters which are Owned pointers. These pointers
are not initialized until in
[Master::initialize|https://github.com/apache/mesos/blob/dcc8bd7d2a942889fe473c21ab64e863d0e6a13f/src/master/master.cpp#L699].
However the metrics, being hosted by a separate actor, can be accessed before
the master is initialized, thus leaving the Owned sorter pointers uninitialized
when called.
I don't see a problem initializing the sorters in the
[HierarchicalAllocatorProcess
constructor|https://github.com/apache/mesos/blob/dcc8bd7d2a942889fe473c21ab64e863d0e6a13f/src/master/allocator/mesos/hierarchical.hpp#L74-L85]?
