Hi everyone.
I’m learning hadoop 2.x technology Hortonworks, cloudera and notice that in architecture of hadoop 2.x there is no Secondary namenode it was replaced by Standby namenode.
1) Is **Secondary node** deprecated ? couse (as I understood) Standby namenode functions differ from Secondary namenode functions.
2) Can I build hadoop without Secondary namenode and without standby namenode and without loss of performance?
Thank you
