The "Hive/HBaseIntegration" page has been changed by JohnSichi. http://wiki.apache.org/hadoop/Hive/HBaseIntegration?action=diff&rev1=5&rev2=6 -------------------------------------------------- * the first column in the Hive table automatically becomes the key in the HBase table * for each subsequent Hive column, the table creator must specify a corresponding entry in the comma-delimited {{{hbase.columns.mapping}}} string (so for a Hive table with n columns, the string should have n-1 entries) - * a mapping entry is of the form {{{column-family-name:[column-type]}}} + * a mapping entry is of the form {{{column-family-name:[column-name]}}} - * if no column-type is given, then the Hive column will map to all columns in the corresponding HBase column family, and the Hive MAP datatype will be used to allow access to these (possibly sparse) columns + * if no column-name is given, then the Hive column will map to all columns in the corresponding HBase column family, and the Hive MAP datatype must be used to allow access to these (possibly sparse) columns - TBD: details on how HBase columns are named within a family, and how - primitive and map values are serialized + TBD: details on how primitive and map values are serialized = Potential Followups =
