LoadIncrementalHFiles now deleting the hfiles?

[Adam Phelps]

We were using a backup scheme for our system where we have map-reduce 
jobs generating HFiles, which we then loaded using LoadIncrementalHFiles 
before making a remote copy of them using distcp.

However we just upgraded hbase (we're using cloudera's package, so we 
went from CDH3B4 to CDH3U0, both of which are versions of 0.90.1), and 
discovered that the HFiles now get deleted by the load operation.  Is 
this a recent change?  Is there a configuration variable to revert this 
behavior?

We can work around it by doing the copy before the load, but that is 
less than optimal in our scenario as we'd prefer to have quicker access 
to the data in HBase.
