Definition

A task which is run when a compute node joins a pool in the Azure Batch service, or when the compute node is rebooted or reimaged.

Remarks

Batch will retry tasks when a recovery operation is triggered on a compute node. Examples of recovery operations include (but are not limited to) when an unhealthy compute node is rebooted or a compute node disappeared due to host failure. Retries due to recovery operations are independent of and are not counted against the MaxTaskRetryCount. Even if the MaxTaskRetryCount is 0, an internal retry due to a recovery operation may occur. Because of this, all tasks should be idempotent. This means tasks need to tolerate being interrupted and restarted without causing any corruption or duplicate data. The best practice for long running tasks is to use some form of checkpointing.
