Key: HAMA-498
URL: https://issues.apache.org/jira/browse/HAMA-498
Project: Hama
Issue Type: Improvement
Components: bsp
Affects Versions: 0.4.0
Reporter: Edward J. Yoon
Fix For: 0.5.0
As described in http://wiki.apache.org/hama/GroomServerFaultTolerance
BSPTask should periodically ping its parent 'GroomServer' for their health
status.
1. If Tasks are unable to ping their parent 'GroomServer', it should be killed
themselves.
2. And, if GroomServer does not receive ping from the childs, GroomServer
should check whether that child is running.
You don't need to implement recovery logic in this issue.
