--------------------------------------
{quote}
If we don't change the reinitialize signature, we might not need setRMContext
at all.
{quote}
[~kkambatl], In this case, we need to call reinitialize() directly from
ResourceManager#serviceInit(). Is it acceptable for us? It means that
Schedulers#serviceInit() doesn't initialize anything. If it's acceptable for
us, I can fix it soon.
{code}
- try {
- scheduler.reinitialize(conf, rmContext);
- } catch (IOException ioe) {
- throw new RuntimeException("Failed to initialize scheduler", ioe);
- }
