------------------------------------
Summary: switch from thread-based container launch to Futures
Key: SLIDER-84
URL: https://issues.apache.org/jira/browse/SLIDER-84
Project: Slider
Issue Type: Improvement
Components: appmaster
Affects Versions: Slider 0.30
Reporter: Steve Loughran
Priority: Minor
The role launching code in the AM is based off Distributed Shell: uses a thread
per launched container. This will have scale limits when launching a very large
cluster if the assignments all come in near-simultaneously.
Switching to a Java futures model would allow the AM to deploy via an executor
that limited the number of operations active; possibly also support a better
shutdown
