Erik Krogen commented on HDFS-13265:
------------------------------------
Attaching branch-2 patch to see if this will actually succeed in Jenkins
despite other branch-2 builds failing.
The trunk patch is still pending fixing all of the test failures... Seems there
are not too many, but they need to be fixed before this can be committed.
> 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.
