Todd Lipcon commented on HBASE-4388:
------------------------------------
A few small comments:
- we should have a constant like META_MIGRATION_CURRENT_VERSION which maps to
the most recent - we can use this when we have completed migration
- it seems to make more sense to have the constants just be ints, and then
convert the cell contents to an int where we do the comparison, rather than
have the constants be byte arrays and use byte array comparison.
> Second start after migration from 90 to trunk crashes
