Chris Douglas commented on HDFS-13265:
--------------------------------------
I'm +1 on the patch, FWIW. If HADOOP-15311 will be in branch-2, then we should
try to apply these in a consistent order and backport it first. If not, then
I'll commit these as they are.
> MiniDFSCluster should set reasonable defaults to reduce resource consumption

> 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.
