Raghu Angadi commented on HADOOP-1506:
--------------------------------------
This should probably be optional. DFS in general wants to enforce the condition
that dfs.block.size should be a multiple of io.bytes.per.checksum. This could
be an issue if we are copying files written in earlier versions. Making this
optional also has the advantage that we could change block size etc if we want
to.
> distcp not preserving the replication factor and block size of source files
