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.
