Eli Collins created YARN-381:
--------------------------------
Summary: Improve FS docs
Key: YARN-381
URL: https://issues.apache.org/jira/browse/YARN-381
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 2.0.0-alpha
Reporter: Eli Collins
Priority: Minor
The MR2 FS docs could use some improvements.
Configuration:
- sizebasedweight - what is the "size" here? Total memory usage?
Pool properties:
- minResources - what does min amount of aggregate memory mean given that this
is not a reservation?
- maxResources - is this a hard limit?
- weight: How is this ratio configured? Eg base is 1 and all weights are
relative to that?
- schedulingMode - what is the default? Is fifo pure fifo, eg waits until all
tasks for the job are finished before launching the next job?
There's no mention of ACLs, even though they're supported. See the CS docs for
comparison.
Also there are a couple typos worth fixing while we're at it, eg "finish. apps
to run"
Worth keeping in mind that some of these will need to be updated to reflect
that resource calculators are now pluggable.
