我JSON文件中follwoing格式：解析豬中複雜的json？
{ "_id" : "foo.com", "categories" : [], "h1" : { "bar==" : { "first" : 1281916800, "last" : 1316995200 }, "foo==" : { "first" : 1281916800, "last" : 1316995200 } }, "name2" : [ "foobarl.com", "foobar2.com" ], "rep" : null }
所以，我如何解析此JSON豬..
也，類別和代表可以有一些字符在it..and可能不永遠是空的。 我做了以下嘗試。
a = load 'sample_json.json' using JsonLoader('id:chararray,categories:[chararray], hostt:{ (variable_a: {(first:int,last:int)})}, ns:[chararray],rep:chararray ');
，但我得到這個錯誤：
org.codehaus.jackson.JsonParseException: Unexpected character ('D' (code 68)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [Source: [email protected]; line: 1, column: 50] at org.codehaus.jackson.JsonParser._constructError(JsonParser.java:1291) at org.codehaus.jackson.impl.JsonParserMinimalBase._reportError(JsonParserMinimalBase.java:385) at org.codehaus.jackson.impl.JsonParserMinimalBase._reportUnexpectedChar(JsonParserMinimalBase.java:306) at org.codehaus.jackson.impl.Utf8StreamParser._handleUnexpectedValue(Utf8StreamParser.java:1582) at org.codehaus.jackson.impl.Utf8StreamParser.nextToken(Utf8StreamParser.java:386) at org.apache.pig.builtin.JsonLoader.readField(JsonLoader.java:173) at org.apache.pig.builtin.JsonLoader.getNext(JsonLoader.java:157) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigRecordReader.nextKeyValue(PigRecordReader.java:211) at org.apache.hadoop.mapred.MapTask$NewTrackingRecordReader.nextKeyValue(MapTask.java:532) at org.apache.hadoop.mapreduce.MapContext.nextKeyValue(MapContext.java:67) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:143) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:764) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:370) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:212)
