---------------------------------------
@Jesse:
HConstants.java has moved to hbase-common
Can you rebase your patch ?
> Don't delete HFiles when in "backup mode"

> Project: HBase
> Issue Type: New Feature

> This came up in a discussion I had with Stack.
> It would be nice if HBase could be notified that a backup is in progress (via
> a znode for example) and in that case either:
> 1. rename HFiles to be delete to <file>.bck
> 2. rename the HFiles into a special directory
> 3. rename them to a general trash directory (which would not need to be tied
> to backup mode).
> That way it should be able to get a consistent backup based on HFiles (HDFS
> snapshots or hard links would be better options here, but we do not have
> those).
> #1 makes cleanup a bit harder.
