Steve Loughran commented on YARN-1564: -------------------------------------- Sync on AtomicBool warnings are spurious; code is simply using the (final) objects as something to wait/notify off to indicate status updates within the atomic values themselves. Nothing wrong with that —avoids having a separate object, and makes it obvious what things are waiting on. Presumably the check is there for people who don't know what they are doing. > add some basic workflow YARN services > ------------------------------------- > > Key: YARN-1564 > URL: https://issues.apache.org/jira/browse/YARN-1564 > Project: Hadoop YARN > Issue Type: New Feature > Components: api > Affects Versions: 2.4.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Minor > Attachments: YARN-1564-001.patch, YARN-1564-002.patch > > Original Estimate: 24h > Time Spent: 48h > Remaining Estimate: 0h > > I've been using some alternative composite services to help build workflows > of process execution in a YARN AM. > They and their tests could be moved in YARN for the use by others -this would > make it easier to build aggregate services in an AM -- This message was sent by Atlassian JIRA (v6.3.4#6332)
