What about just storing some metadata in a special table?
Then on you second job startup you can read that meta data and set your scan
/input splits appropriately?

Subject: Re: Observer/Observable MapReduce
David,
how about waking up my second map reduce job as soon as I see some rows updated
in that table.
any thoughts on observing a column update?
thanks
Instead of using a table, how about using the available ZooKeeper
service itself? They can hold small bits of information pretty well
themselves.
