json - 风筝SDK : Getting error while Json-import

Question

我在使用 kite sdk 导入 json 时遇到问题。

使用命令生成 avro 模式:

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

然后通过命令在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，我正在运行以下命令:

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

获取错误:

任何人都可以帮助我理解出了什么问题吗？？？ 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。

而且Kite SDK在1.1.0版本之后就没有新的发布了，而且这次发布也是在2015年6月。
