Review comment:
After reading the helix code carefully, `TaskResult.FAILED` is
equivalent to `TaskPartitionState.TASK_ERROR `, `TaskResult.FATAL_FAILED` is
equivalent to `TaskPartitionState.TASK_ABORTED`. So `FATAL_FAILED ` seems the
best choice for us, if we don't check CRC first, the task will be in
`FATAL_FAILED ` when uploading anyway.
