> The tests seem to fail bcoz , when the datanode goes down with stale node interval being
set to a low value, containers may get closed early and client writes might fail with closed
container exception rather than pipeline failure/Timeout exceptions as excepted in the tests.
The fix made here is to tune the stale node interval.
