Hi Shashwat ! I am getting host name as chn-29-24. My host config is : 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 10.86.29.24 chn-29-24 chn-29-24.mmt.mmt I have already formatted namenode successfully. I am not sure where to change the port number, bcoz i have not configured 6500 any where. Thanks in advance for helping me out.
