Summary: Configuring minimum-allocation-mb at queue level
Key: YARN-5900
URL: https://issues.apache.org/jira/browse/YARN-5900
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Manikandan R
Motivation for proposing minimum-allocation-mb at queue level in the form of
yarn.scheduler.capacity.<queue-path>.minimum-allocation-mb
is, when the queue structure has been designed on resource usages (only memory
for now). For example, there could be three segments like small, medium & large
jobs and queues can be created for each segment accordingly. With this, it
would be good to configure the min container size of each queue separately. For
example, For small, it is 1 GB, For medium, it is 3 GB, For large, it can be 6
GB.
Would this simplify container release process and its overall management,
eventually reduces no. of containers running at any moment?
