dfs.namenode.replication.min can set by client while reading/writing
hdfs files
Hi,
Can I set dfs.namenode.replication.min on client side?
or
It can only be set on namenode?
Is there any docs available that separates configs that we can use in:
1. namenode
2. datanode
3. hdfs client (for read and write hadoop files)

It’s a system wide setting.
Yes it is configurable. No it is general a bad idea to change it for
anything other than 1. Hadoop has not been properly tested with this value
set to 2 or above.
We really should update the description of this config and say “no, you
really don’t want to change it”
