How to restore geomesa index table in accumulo?

Question

In my accumulo db 2 index tables are lost: ...02726, ...02727. My namespace does not have it but in geomesa tables they are present. Why this can happen and how to restore them? I can't get data through the util

geomesa-accumulo export

My accumulo data

root@accumulo myNamespace.geomesa> tables -ns myNamespace

It's hard to say why the tables are not there, I would guess something went wrong with your cluster as GeoMesa does not delete tables AFAIK.

To restore the export functionality, delete the references to the missing tables out of your catalog through the Accumulo shell, or create new empty tables that match the expected names.
