Pranav, Having a corrupt root table and replacing with with an empty empty file means Accumulo does not not anything about the metadata table. Without the metadata table, Accumulo know nothing about the other tables.
If you can do so, I suggest starting over. If you have data you need to keep, you can bulk import the existing RFiles into a new instance if you can associate the files to a table. Having the old splits would be helpful but is not necessary. What version of Accumulo are you using? Take a look at https://accumulo.apache.org/1.9/accumulo_user_manual.html#_advanced_system_recovery . It would be good to understand what led to the corruption in the accumulo.root table.
