Dependency change: Upgraded
org.btrplace/scheduler-apito0.46.Dependency change: Upgraded
org.btrplace/scheduler-chocoto0.46.Dependency change: Excluded ClojureScript from clj-fuzzy dependencies.
Design change: Implemented peer-group ZooKeeper connection sharing. This reduces the number of ZooKeeper connections required per machine, and improves scheduler performance.
Enhancement: Tasks now time out when being stopped, allowing a peer to be rescheduled in cases where the task is stuck. This is configured via the peer-config
:onyx.peer/stop-task-timeout-ms.Enhancement: A message is now emitted to the logs when a job is submitted, but does not start because of the scheduler gave it no peers.
