> TestDecommissioningStatus BindException Failure
> -----------------------------------------------

> Key: HDFS-10755
> URL: https://issues.apache.org/jira/browse/HDFS-10755
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Eric Badger
> Assignee: Eric Badger
> Attachments: HDFS-10755.001.patch, HDFS-10755.002.patch
>
>
> Tests in TestDecomissioningStatus call MiniDFSCluster.dataNodeRestart(). They
> are required to come back up on the same (initially ephemeral) port that they
> were on before being shutdown. Because of this, there is an inherent race
> condition where another process could bind to the port while the datanode is
> down. If this happens then we get a BindException failure. However, all of
> the tests in TestDecommissioningStatus depend on the cluster being up and
> running for them to run correctly. So if a test blows up the cluster, the
> subsequent tests will also fail. Below I show the BindException failure as
> well as the subsequent test failure that occurred.
