Vitaly Kruglikov commented on YARN-381: --------------------------------------- The file FairScheduler.apt.vm doesn't specify the units for the "minResources" property in queue allocations. Is it in megabytes or in bytes? > 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. -- This message is automatically generated by JIRA.
