I guess ur confusing data node with task tracker. If a task tracker
fails the job tracker assigns the task to other task trackers.. and the
block copy/replication ur refering to, is related datanodes.

Hi,
Task tracker failover happens but alive slave instance firstly does copy
the blocks locally and then recover that. Therefore due to copy
operation it
takes 7-10 minutes for my test case. To me it looks to be more. Can we
have
fastest failover and resume the operation
quickly? Is there anyway to tweak the configuration??
Thanks
