Dear Wiki user, You have subscribed to a wiki page or wiki category on "Pig Wiki" for change notification.
The following page has been changed by EarlCahill: http://wiki.apache.org/pig/PigLatin ------------------------------------------------------------------------------ * You can specify more complex schemas in the AS clause (see PigLatinSchemas). * If your records are stored in some special format that our functions can't parse, you can of course write your own storage function (see PigFunctions). * In Pig, relations are ''unordered'', which means we do not guarantee that tuples are processed in any particular order. (In fact, processing may be parallelized, in which case tuples are not processed according to ''any'' total ordering.) - * If you pass a directory name to LOAD, it will load all files within the directory. + * If you are in hadoop mode and pass a directory name to LOAD, it will load all files within the directory. (Throws an exception in local mode.) * You can use hadoop supported globbing to specify a file or list of files to load. See [http://lucene.apache.org/hadoop/api/org/apache/hadoop/fs/FileSystem.html#globPaths(org.apache.hadoop.fs.Path)the hadoop glob documentation] for details on globbing syntax. Globs can be used at the file system or directory levels. (This functionality is available as of pig 1.1e.)
