Steve Loughran commented on HDFS-9407:
--------------------------------------
its not just that there may not have been an NN shutdown, we are moving yetus
and jenkins to builds in parallel.
Tests cannot assume that the default port is free for use. Instead they should
look for a free port and use that across the sequences of instances of their
NNs.
yes, there's still a risk that the port there can get bound in a race condition
with other test runs, but hard coding the default is significantly more brittle
