Siddharth Seth commented on HIVE-16927:
---------------------------------------
[~prasanth_j] - I don't think we make a permanent change of this being set to
0. A bad instance will never stop on it's own, and will keep trying to launch
new containers.
A better default would likely be numInstances, while making sure it is not too
low (6 is the default for example), and the value is high enough to allow a
node to be blacklisted.
Option1: numInstances * threshold to mark a node as disabled.
Option2: max(6, max(numInstances, threshold to mark a node as disabled))
Option3: ?
An enhancement request to Slider to get better control over this
