The "Hive/StorageHandlers" page has been changed by JohnSichi. http://wiki.apache.org/hadoop/Hive/StorageHandlers?action=diff&rev1=2&rev2=3 -------------------------------------------------- = Open Issues = - * The storage handler class name is currently saved to the metastore via table property {{{storage_handler}}}; this should probably be a first-class attribute on MTable instead + * The storage handler class name is currently saved to the metastore via table property {{{storage_handler}}}; this should probably be a first-class attribute on MStorageDescriptor instead * Names of helper classes such as input format and output format are saved into the metastore based on what the storage handler returns during CREATE TABLE; it would be better to leave these null in case they are changed later as part of a handler upgrade * A dummy location is currently set for a non-native table (the same as if it were a native table), even though no Hive files are created for it. We would prefer to store null, but first we need to fix the way data source information is passed to input formats (HIVE-1133) * Storage handlers are currently set only at the table level. We may want to allow them to be specified per partition, including support for a table spanning different storage handlers.
