HI Nitin

>>did you start the cluster with replication factor 3 and later changed it
to 2
yes correct. We have only two datanode, First  I wrongly configured after I
changed  to 2.
and i have done with hadoop fs -setrep -R 2 /myfolder

same thing i done in all folder in HDFS
>>did you enable rack awareness
no.

Did I learn something today? If not, I wasted it.
