>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: datanode, namenode, test
>            Reporter: Erik Krogen

>            Priority: Major

> MiniDFSCluster takes its defaults from {{DFSConfigKeys}} defaults, but many of these
are not suitable for a unit test environment. For example, the default handler thread count
of 10 is definitely more than necessary for (almost?) any unit test. We should set reasonable,
lower defaults unless a test specifically requires more.
