Question

使用kite sdk导入json时遇到问题。

使用命令生成avro架构：

./kite-dataset json-schema /vagrant/satyam/kite/restaurant-sample.json  -o sample.avsc --record-name HGW

然后传递命令在hdfs文件系统中创建数据集：

./kite-dataset create dataset:hdfs:/user/falcon/datasets/hgw --schema sample.avsc

要导入JSON文件，我按照以下命令运行：

./kite-dataset -v json-import /vagrant/satyam/kite/restaurant-sample.json dataset:hdfs:/user/falcon/datasets/hgw

获取错误：

任何人都可以帮我解释出错的地方??? 提前致谢

我认为您使用的是Kite SDK 1.1.0版本。我在做csv-import时也遇到了同样的错误。当我切换到Kite SDK 1.0.0版本时，没有出现这样的错误。

我建议您切换到Kite SDK 1.0.0版本。

此外，在1.1.0版本之后没有新版Kite SDK，甚至此版本也发布于2015年6月。
