Getting started with downloading stable distribution of hadoop from this link.
Followed setups mentioned here
Caveats, required for my personal setup
On OS X please make sure that we can ssh localhost without requiring a password. If password is prompted then the below mentioned steps have to be followed
Check if you have already generated key for using it at some other source. If you have id_rsa.pub available at ~/.ssh/, in which case do the following
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
With this you should be able to use
ssh localhost
Without requiring to enter any password
I created separate pseudo distributed configurations here with this configurations there was no mention that capacity-scheduler.xml is required too but resource-manager instance was failing instantiation and reason was non-occurrence of this file.
