----------------------------------
Summary: 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
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.
