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.
