Yin Huai created SPARK-14129:
--------------------------------
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.
