Debugging an aggregator
I've been running my first few trivial programs by just running them
in Eclipse. (They are just writing.) It seems to me that I'll never
get away with this once I create an aggregator. What's the drill?

Eventually I'll need that, I think. Off to read.

Drop your jar in lib/ext in the accumulo directory on all the servers.

Once I have it debugged in mock, then what? Presumably it has to get
into the classpath of my accumulo processes. How's that organized?

You can use Mock Accumulo to test iterators and aggregators in unit test.
Look at org.apache.accumulo.core.client.mock.MockConnectorTest.testAggregation()
in src/core/src/test/java/ for an example.
Mock Accumulo was first introduced in 1.3. Its a little rough around
the edges in 1.3, its more mature in 1.4. I think it will meet your
needs, but let us know if you run into issues.
If you are writing code that runs against a live instance, you can use
connector.tableOperations() to setup and configure Aggregators.
