Mikhail Petrov commented on IGNITE-12907:
-----------------------------------------
[~agura], could you clarify, please. I see no {{registerWalker()}} method in
GridSystemViewManager and ConcurrentHashMap is used to store the SystemView at
current master. Does this mean that the problem has been already solved?
> GridSystemViewManager is not thread safe

>
> {{GridSystemViewManager}} is not thread safe because it allows to registers
> walkers using public {{registerWalker()}} that just adds walker to a
> {{HashMap}}.
> It seems the simplest solution here: make {{registerWalker()}} method private
> because it has usages only from {{GridSystemViewManager}} constructor.
