Subject [Hadoop Wiki] Update of "ZooKeeper/GSoCFailureDetector" by AbmarBarros
Date Wed, 05 May 2010 15:01:13 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "ZooKeeper/GSoCFailureDetector" page has been changed by AbmarBarros.


  ZooKeeper servers detect the failure of other servers and clients by counting the number
of 'ticks' for which it doesn't get a heartbeat from other machines. This is the 'timeout'
method and it works very well; however it is possible that it is too aggressive and not easily
tuned for some more unusual ZooKeeper installations. This project's goals are to abstract
the failure detector to a separate module, to implement several failure detectors and to compare
their appropriateness for ZooKeeper.
- The full project proposal is attached to this page.
