Karthik Kambatla created YARN-4526: -------------------------------------- Summary: Make SystemClock singleton so AppSchedulingInfo could use it Key: YARN-4526 URL: https://issues.apache.org/jira/browse/YARN-4526 Project: Hadoop YARN Issue Type: Sub-task Components: scheduler Affects Versions: 2.8.0 Reporter: Karthik Kambatla Assignee: Karthik Kambatla
To track the time a request is received, we need to get current system time. For better testability of this, we are likely better off using a Clock instance that uses SystemClock by default. Instead of creating umpteen instances of SystemClock, we should just reuse the same instance. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
