When a new snapshot is created it is added to the cluster state as a snapshot-in-progress in INIT state, and the initialization is kicked off in a new runnable task by SnapshotService.beginSnapshot(). The initialization writes multiple files before updating the cluster state to change the snapshot-in-progress to STARTED state. This leaves a short window in which the snapshot could be deleted (let's say, because the snapshot is stuck in INIT or because it takes too much time to upload all the initialization files for all snapshotted indices). If the INIT snapshot is deleted, the snapshot-in-progress becomes ABORTED but once the initialization in SnapshotService.beginSnapshot() finished it is change back to STARTED state again. This commit avoids an ABORTED snapshot to be started if it has been deleted during initialization. It also adds a test that would have failed with the previous behavior, and changes few method names here and there. |
