#2791 readytorelease enhancement

Checkpointing within Hive slaves should be improved

Reported by: jkarder Owned by: jkarder
Priority: medium Milestone: HeuristicLab 3.3.15
Component: Hive.Slave Version: 3.3.14
Keywords: Cc:


During checkpointing, the slave pauses the task, updates its task data on the server and resumes the same task immediately. However, the slave should pause the task, send it back to the server and receive another task (may be the same if no others are available).

r15004: improved checkpointing (task is paused and sent back to the server, new one is assigned via next heartbeat)

comment:3 Changed 4 weeks ago by jkarder

Currently, the following default settings are used:

  • CheckpointInterval (time of continuous calculation after which a task is sent back): 18 Hours
  • CheckpointCheckInterval (time between checks whether or not a task should be sent back): 5 Minutes

If required, I can adjust these as well.
