-------------------------------------
Summary: Use nodemap to build up location restrictions on AA
placement
Key: SLIDER-967
URL: https://issues.apache.org/jira/browse/SLIDER-967
Project: Slider
Issue Type: Sub-task
Components: appmaster
Affects Versions: Slider 0.90
Reporter: Steve Loughran
Assignee: Steve Loughran
Fix For: Slider 0.90
This is the key AA placement work: AA placement requests to use nodemap to
build up the explicit list of suitable nodes, while excluding
# all nodes where there's an instance already
# all nodes with an outstanding request
# all nodes considered failed
For now, let's include those considered "unreliable", as in having launches
fail recently.
The list to submit should be *all nodes with the target label expression*. This
means that we'll have to use the label information in the nodemap and requests
& do some matching in the AM first.
Also: stop listing all the changed nodes on a nodemap update...just the first
10 should be enough.
