------------------------------------------
> MiniDFSCluster should set reasonable defaults to reduce resource consumption

> Key: HDFS-13265
> URL: https://issues.apache.org/jira/browse/HDFS-13265
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode, namenode, test
> Reporter: Erik Krogen
> Assignee: 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.
