I have set the replication factor for my file as follows:

hadoop fs -D dfs.replication=5 -copyFromLocal file.txt /user/xxxx

When a NameNode restarts, it makes sure under-replicated blocks are replicated. Hence the replication info for the file is stored (possibly in nameNode). How can I get that information?

Try to use command hadoop fs -stat %r /path/to/file, it should print the replication factor.
