Hadoop 2.2.0, two computer, one is master,another is node1. I want to know
following scene:
If node1 is down by some reason, but I don't know node1 can't work, then I use
hadoop command to put a file,such as:
$ hadoop fs -put graph.txtgraphin/graph.txt
I know graph.txt file will be put master m
Hi Edward,
You can't achieve data consistency on your cluster configuration. To do
this you need at least 3 data nodes and enabled replication with level 3
( dfs.replication property in hdfs-site.xml).

Edward,
It doesn't seem like your "hadoop -put ..." command will even complete -
the master isn't receiving the file at any point. It instructs the node1 to
connect to the client, after asking the node1 if it is in a state that it
can receive data to be written, which depends on several other daem
