Billie Rinaldi updated SLIDER-1199:
-----------------------------------
    Attachment: SLIDER-1199.1.patch

Submitting a preview patch for discussion. I am not very familiar with this area (neither Slider role placement nor RM blacklisting), so any ideas / comments would be appreciated. Still trying to figure out how to test this, as well. cc [~gsaha], [~stevel@apache.org]

> From the code, it seems like when the node failure threshold for a role is exceeded, that node is no longer suggested for placement. But there is nothing preventing the RM from selecting the node again. If the node were blacklisted, perhaps that would prevent new allocations on problem nodes.
