Subject [jira] [Commented] (HAMA-370) Failure detector for Hama
Date Wed, 23 Mar 2011 05:40:05 GMT

    [ https://issues.apache.org/jira/browse/HAMA-370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010005#comment-13010005

ChiaHung Lin commented on HAMA-370:
-----------------------------------

If I understand correctly, HAMA-363 seems to be relating to network monitoring, whose responsibility
is to monitor network and alert administrators when events raise; but the purpose of failure
detector is to detect node crashes in a distributed system.
