Roni Burd commented on YARN-6245: --------------------------------- Sounds good guys. I'm having some issues with the change in trunk (I was based off 2.7) and need to refactor out the 2 changes. Will post the patch ASAP > Add FinalResource object to reduce overhead of Resource class instancing > ------------------------------------------------------------------------ > > Key: YARN-6245 > URL: https://issues.apache.org/jira/browse/YARN-6245 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Wangda Tan > Attachments: observable-resource.patch, > YARN-6245.preliminary-staled.1.patch > > > There're lots of Resource object creation in YARN Scheduler, since Resource > object is backed by protobuf, creation of such objects is expensive and > becomes bottleneck. > To address the problem, we can introduce a FinalResource (Is it better to > call it ImmutableResource?) object, which is not backed by PBImpl. We can use > this object in frequent invoke paths in the scheduler. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
