Subject RE: accumulo.root invalid table reference [SEC=UNOFFICIAL]
Date Tue, 21 Feb 2017 01:00:01 GMT

In case it is ok to remove these from the root table, how can I scan the root table for rows
with a rowid starting with !0;1vm?  

Running "scan -b !0;1vm" throws an exception and exits the shell.

Does that mean I should have entries for 1vm in the metadata table corresponding to the root

We are running 1.6.5

The root table should only reference the tablets in the metadata table. 
It's a hierarchy: like metadata is for the user tables, root is for the metadata table.

What version are ya running, Matt?
