--------------------------------

             Summary: [Table related commands] Alter table
                 Key: SPARK-14129
                 URL: https://issues.apache.org/jira/browse/SPARK-14129
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Yin Huai


For alter table command, we have the following tokens. 
TOK_ALTERTABLE_RENAME
TOK_ALTERTABLE_LOCATION
TOK_ALTERTABLE_PROPERTIES/TOK_ALTERTABLE_DROPPROPERTIES
TOK_ALTERTABLE_SERIALIZER
TOK_ALTERTABLE_SERDEPROPERTIES
TOK_ALTERTABLE_CLUSTER_SORT
TOK_ALTERTABLE_SKEWED

For a data source table, let's implement TOK_ALTERTABLE_RENAME, TOK_ALTERTABLE_LOCATION, and TOK_ALTERTABLE_SERDEPROPERTIES. We need to decide what we do for TOK_ALTERTABLE_PROPERTIES/TOK_ALTERTABLE_DROPPROPERTIES. It will be use to allow users to correct the data format (e.g. changing csv to com.databricks.spark.csv to allow the table be accessed by the older versions of spark).

For a Hive table, we should implement all commands supported by the data source table and TOK_ALTERTABLE_PROPERTIES/TOK_ALTERTABLE_DROPPROPERTIES.

For TOK_ALTERTABLE_CLUSTER_SORT and TOK_ALTERTABLE_SKEWED, we should throw exceptions.
