Tanping Wang commented on HDFS-1773:
------------------------------------
The failed core test cases are irrelevant to this patch. Among them,
org.apache.hadoop.hdfs.server.namenode.TestBackupNode
org.apache.hadoop.hdfs.TestDatanodeBlockScanner
org.apache.hadoop.hdfs.TestDFSStorageStateRecovery
org.apache.hadoop.hdfs.TestFileConcurrentReader
are also seen failing with other just posted patches.
org.apache.hadoop.hdfs.TestInjectionForSimulatedStorage
org.apache.hadoop.hdfs.TestReadWhileWriting
I run them manually and they are passing.

> Our service engineering team who operates the clusters on a daily basis
> founds it is confusing that after a data node is decommissioned, there is no
> way to make the cluster forget about this data node and it always remains in
> the dead node list.
