             Summary: Improve error logging when restoring a table with "impala::" prefix
                 Key: KUDU-3299
                 URL: https://issues.apache.org/jira/browse/KUDU-3299
             Project: Kudu
          Issue Type: Improvement
          Components: backup
            Reporter: Abhishek


When a kudu table created through impala is backed up in a cluster without Kudu+HMS integration, it will be containing the "impala::" prefix. If this table backup is restored in a cluster with Kudu+HMS integration in place it fails with the below error message:

 
{code:java}
ERROR backup.KuduRestore$: Failed to restore table impala::default.my_first_table: Look back in the logs for the full exception. Error: Failure(org.apache.kudu.client.NonRecoverableException: failed to create HMS catalog entry for table  [id=077ea8941ffa49aea5b934dbaa890f9c]: when the Hive Metastore integration is enabled, Kudu table names must be a period ('.') separated database and table name identifier pair, each containing only ASCII alphanumeric characters, '_', and '/': impala::default.my_first_table){code}
 


In this scenario it would be helpful if we can present the option of removing "impala::" prefix as a part of the above error message (–removeImpalaPrefix). This option is available as a part of the restore job
