----------------------------------------------------------------
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)
