Error starting Looker: Table/Column already exists

Userlevel 3

Last tested: Nov 7, 2017

This error sometimes shows up in the logs when a migration is halted before it completes and Looker starts the migration over again upon net startup:

[ERROR | <threadid> | main] :: Error starting Looker: Java::JavaSql::SQLSyntaxErrorException: Table '<tablename>'/ Column '<column_name>' already exists

You need to restore from a backup when this happens.
