> Integration tests run multiple datanodes in the same JVM.  Each datanode comes with 60 chunk writer threads by default (may be decreased in HDDS-3053).  This makes thread dumps (eg. produced by {{GenericTestUtils.waitFor}} on timeout) really hard to navigate, as there may be 300+ such threads.
> Since integration tests are generally run with a single disk which is even shared among the datanodes, a few threads per datanode should be enough.
