And? What is the intent? To change them? Thanks.
{quote}
Yes. There is a JIRA HBASE-16458.

You understand how someone might think 'MR' when they see 'Job'. Do you want to
prevent any confusion?
{quote}
We have had already long discussion about this topic in the past. Should we
start it again?
Originally it was Service, then - Task, now is Job. What do you suggest, stack?
{quote}
And if the client goes away? They query to find running jobs?
{quote}
Job will fail, but next time (run), repair will be started automatically
(mostly cleanup stuff). We have repair tool, just in case if "client goes away"
or some other disaster happens.

> User can merge incremental backup images into single incremental backup image.
> # Merge supports only incremental images
> # Merge supports only images for the same backup destinations
> Command:
> {code}
> hbase backup merge image1,image2,..imageK
> {code}
> Example:
> {code}
> hbase backup merge backup_143126764557,backup_143126764456
> {code}
> When operation is complete, only the most recent backup image will be kept
> (in above example - backup_143126764557) as a merged backup image, all other
> images will be deleted from both: file system and backup system tables,
> corresponding backup manifest for the merged backup image will be updated to
> remove dependencies from deleted images. Merged backup image will contains
> all the data from original image and from deleted images.
