Subject Re: LoadIncrementalHFiles now deleting the hfiles?
Date Thu, 28 Apr 2011 23:28:28 GMT
I took a look through the code and don't see any explicit removes and
looking through history of changes to the file, I don't see any change
of substance.

Can you figure what is doing the delete? At what stage?  Is it as
completebulkload runs?
