bq. It's not creating 12 separate MiniMR clusters. 

Pardon. It is launching distinct MR jobs, though, clearly. (Under Hadoop 2, that's a new AM,
and workers, etc.)

bq. It seems to me that each test runs its own scan and then reports success/failure. I would
assume that counts as a kind of heart-beat to indicate the test is still operating.

There is a global timeout of 900 seconds (forkedProcessTimeoutInSeconds). If the forked process
has not terminated by then, the child is killed and the test is marked as timed out.

> bq. It looks like since this change org.apache.hadoop.hbase.mapreduce.TestTableInputFormatScan
has not passed a single time in the EC2 builds (http://54.241.6.143/job/HBase-0.94/). Change
was introduced in Build #72, since then this tests times out (or doesn't finish)
