Summary: Fairscheduler: Dump scheduler state in log
Key: YARN-6042
URL: https://issues.apache.org/jira/browse/YARN-6042
Project: Hadoop YARN
Issue Type: Improvement
Components: fairscheduler
Reporter: Yufei Gu
Assignee: Yufei Gu
To improve the debugging of scheduler issues it would be a big improvement to
be able to dump the scheduler state into a log on request.
The Dump the scheduler state at a point in time would allow debugging of a
scheduler that is not hung (deadlocked) but also not assigning containers.
Currently we do not have a proper overview of what state the scheduler and the
queues are in and we have to make assumptions or guess
The scheduler and queue state needed would include (not exhaustive):
instantaneous and steady fair share (app / queue)
AM share and resources
weight
app demand
application run state (runnable/non runnable)
last time at fair/min share
