Hi all,
I'm having a little problem with our tests that use hbase.
First, I run a test which generate all of the hbase tables, and exits.
Then for each test, I copy over the hbase directory, and the start up hbase.
So far, so good, hbase quickly starts up and finds all my tables.
However, I then get NotServingRegion exceptions for the next minute or
so. Afterwards the regions get assigned, and everything is fine.
Looking at the logs, just before the regions start to come online, I see:

My question: what is going on here, and how can I speed it up?
