Re: Block location in HDFS

With the default replication/block placement policy, all replicas are
anyway kept in separate nodes. Is that what you want?

Or are you looking to specify a list of locations you want your blocks
to go to? For the latter, there's no easy way but you may be
interested in https://issues.apache.org/jira/browse/HDFS-385. But you
can't send meta-info with each write with hints even with HDFS-385,
and may need an external system.
