-------------------------------------
Summary: Include node failure history when choosing placement hints
Key: SLIDER-743
URL: https://issues.apache.org/jira/browse/SLIDER-743
Project: Slider
Issue Type: Improvement
Components: appmaster
Affects Versions: Slider 0.60
Reporter: Steve Loughran
Fix For: Slider 0.70
Use the (collected) history on per-node failures to tune placement requests, so
that even if there's a history of components running there, if its been failing
recently then it's not asked for
# Add a "recent failures" field to the node entries, alongside the "total
failures" counter
# the scheduled failure count resetter will set that field to zero,alongside
the component failures
# When Slider has to request a new container, if a node has a recent failure
count above some threshold, it will not be requested, even if it is a past
location of that component.
When the placement policy is STRICT, node failure history will not be taken
into account
