Don't delete HFiles when in "backup mode"
-----------------------------------------
Key: HBASE-5547
URL: https://issues.apache.org/jira/browse/HBASE-5547
Project: HBase
Issue Type: New Feature
Reporter: Lars Hofhansl
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.
