Examples of org.apache.pig.StoreFuncInterface.checkSchema()

org.apache.pig.StoreFuncInterface.checkSchema()
Set the schema for data to be stored. This will be called on the front end during planning if the store is associated with a schema. A Store function should implement this function to check that a given schema is acceptable to it. For example, it can check that the correct partition keys are included; a storage function to be written directly to an OutputFormat can make sure the schema will translate in a well defined way. @param s to be checked @throws IOException if this schema is not acceptable. It should includea detailed error message indicating what is wrong with the schema.
