             Summary: Support native execution of SHOW DATABASE command and fix SHOW TABLE to use table identifier pattern
                 Key: SPARK-14184
                 URL: https://issues.apache.org/jira/browse/SPARK-14184
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Dilip Biswal


Need to address the following two scenarios.

1. Support native execution of SHOW DATABASES 
2. Currently native execution of SHOW TABLES is supported with the exception that identifier_with_wildcards is not passed to the plan. So
SHOW TABLES 'pattern' fails.

The syntax for SHOW commands are described in following link:
