Arpit Agarwal updated HDFS-6768:
--------------------------------
Description:
TestBlockRecovery uses hard-coded port numbers making it susceptible to 'port
in use' errors [as seen
here|https://builds.apache.org/job/PreCommit-HDFS-Build/7484//testReport/org.apache.hadoop.hdfs.server.datanode/TestBlockRecovery/testRaceBetweenReplicaRecoveryAndFinalizeBlock/]
{code}

TestRefreshCallQueue and TestGenericRefresh also use the same hard-coded port
number (54222) which can result in 'port in use' errors with parallel-tests.
