Subject Re: HConstants.FILE_SYSTEM_VERSION on trunk

That's a good question - as far as I know, the on disk format hasnt
changed since KeyValue was introduced. Despite the change of this
constant, there hasnt been any change in the actual on disk format...
.regioninfo aside (which get backfilled anyways if they are missing).

incompatible filesystem changes before this is put back to "7"? To be able to run latest trunk
without losing a week's worth of accumulated data, I have been running with a local patch
which maintains HConstants.FILE_SYSTEM_VERSION at "7".
