[jira] [Created] (SPARK-15978) Some improvement of "Show Tables"

Bo Meng created SPARK-15978:
-------------------------------

             Summary: Some improvement of "Show Tables"
                 Key: SPARK-15978
                 URL: https://issues.apache.org/jira/browse/SPARK-15978
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Bo Meng
            Priority: Minor


I've found some minor issues in "show tables" command:
1. In the SessionCatalog.scala, listTables(db: String) method will call listTables(formatDatabaseName(db), "*") to list all the tables for certain db, but in the method listTables(db: String, pattern: String), this db name is formatted once more. So I think we should remove formatDatabaseName() in the caller.
2. I suggest to add sort to listTables(db: String) in InMemoryCatalog.scala, just like listDatabases().

I will make a PR shortly.
