Konstantin Shvachko updated HADOOP-3282:
----------------------------------------
Attachment: TestCheckpointPorts.patch
I wrapped all startup calls for name- and secondary nodes, and uniformly set
ports to 0 rather than setting it individually before each call.
> TestCheckpoint occasionally fails because of the port issues.

> This is related to timing issues. If MiniDFSCluster does not stop fast enough
> the name-node won't start because the port is busy.
> So the tests should reset the configuration port properties before each
> server startup, because servers change those values to the actual port
> numbers they run.
