I might be wrong, but my assumption is running SN either in 64/32 shouldn't matter. But I am curious how two instances of Secondary namenode is setup, will both of them talk to same NN and running in parallel? what are the advantages here. Wondering if there are chances of image corruption.

Also, do shud I be aware of any other issues for migrating over to 64 bit namenode Thanks in advance for all the suggestions -Sagar
