Key: HADOOP-5784
URL: https://issues.apache.org/jira/browse/HADOOP-5784
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Reporter: Owen O'Malley
Assignee: Amareshwari Sriramadasu
Fix For: 0.21.0

Attachments: patch-5784-1.txt, patch-5784.txt


Currently, the hearbeat cycle is set to (# nodes / 100) in seconds. This can be too long for clusters that need to run low latency jobs. We should make the number of heartbeats that should arrive a second configurable.
