Symptom
- When using the Impala Adapter, while creating a virtual table that contains an Impala “reserved words” on an Impala table or column name, the virtual table creation fails with errors. The error trace below is an example of an error when you attempt to create a virtual table on Impala Tables names "data" and "replication" respectively:
