: Multiple DataNodes on a single machine .
Ist works fine 2 datanodes are up and running .
So i have 2 conf Folders conf and conf2 in hadoop-home .
If i have to set dfs.replication value to 3 - in which hdfs-site.xml
should i set ?
should it be hdfs-site.xml in conf or conf2 .
what should
Hello friends ,

Just for the record, I appreciate that having multiple DataNodes on a
single machine defeats the purpose or the advantages given by having
them spread across machines across racks. I intend to go to that model
as we grow
can run multiple DataNodes on a single machine
each assigned a separate disk that would give me the protection I need
against disk failure.
Can anyone give me any insights in to how I would setup multiple
DataNodes to run on a single machine? Thanks in advance,

Hello Arv,
It is possible to run multiple datanodes on a single machine, and this can be
useful for small-scale test scenarios. Also you mentioned in your previous
message that you have a Hadoop implementation with only one physical datanode
server and want to replicate within it, between
