FAQ
Hi all,

I had some queries :

1) In a Hadoop cluster, when I write a file into HDFS, the replication
factor that's followed - is it corresponding to the dfs.replication
parameter set in hdfs-site.xml file in the master ? Or should
something else be done about that (like changing the dfs.replication
parameter of all the nodes in the cluster by editing the xml file ?)

2) dfs.replication = 2 does that mean there are 2 replicates and a
total of 3 copies / does that mean total number of copies = 2 ?

Thanks,
Ankita
