-------------------------------------------------------------------
Key: HADOOP-1232
URL: https://issues.apache.org/jira/browse/HADOOP-1232
Project: Hadoop
Issue Type: Bug
Reporter: Hairong Kuang
After a datanode shuted down, the following exception was thrown when a job
tried to open a file with blocks on the data node. It looks that the datanode
was removed from NetworkTopology but not from the blockMap.
org.apache.hadoop.ipc.RemoteException: java.io.IOException:
java.lang.IllegalArgumentException: Unexpected non-existing data node:
