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. http://wiki.apache.org/hadoop/ZooKeeper/GSoCFailureDetector?action=diff&rev1=9&rev2=10 -------------------------------------------------- * The FD will run in a more independent way, and it will notify the application of changes using listeners or callbacks. If it runs in the same thread, the application must signal the failure detector of changes, and also retrieve its status periodically. In other words, the application code will be coupled to FD code. * Decided to use the FD on the same thread of the application + ==== How to use application message in adaptive failure detectors? ==== + + ==== Due to the usage of application messages as heartbeat, the actual heartbeats are not sent regularly. How to compute the next estimated arrival time? ==== + + ==== How to report sampling window statistical data from Learners to Leader? ==== + + == Future work == + * Update C client to use the Failure Detector module. This may require to have all failure detectors implemented in C. [[https://issues.apache.org/jira/browse/ZOOKEEPER-848]] + * Analyze the overhead of the timeout computation on adaptive FDs. + * Contrast adaptive FDs behaviour with sampling window full and in a warm-up period (when sampling window is not full). +
