MiniDFSCluster.stopDataNode will always shut down a node in the cluster if a
matching name is not found
-------------------------------------------------------------------------------------------------------
Key: HADOOP-3896
URL: https://issues.apache.org/jira/browse/HADOOP-3896
Project: Hadoop Core
Issue Type: Bug
Reporter: Steve Loughran
The stopDataNode method will shut down the last node in the list of nodes, if
one matching a specific name is not found
This is possibly not what was intended. Better to return false or fail in some
other manner if the named node was not located
synchronized boolean stopDataNode(String name) {
int i;
for (i = 0; i < dataNodes.size(); i++) {
DataNode dn = dataNodes.get(i).datanode;
if (dn.dnRegistration.getName().equals(name)) {
break;
}
}
return stopDataNode(i);
}
