s3distcp: Boş dize yol oluşturmaktır edemez

Question

HDF'ler için S3 s3distcp çalışırken:

sudo -u hdfs hadoop jar /usr/lib/hadoop/lib/s3distcp.jar --src s3n://workAAAA-KKKK-logs/production-logs/Log-XXXX-click/Log-XXXXX-click-2013-03-27_06-21-19_i-7XXb2x39_00037.gz --dest hdfs:///test/ 

Ben şu istisna olsun.

Yol sözdizimimde (s3n: //; hdfs: ///) bir sorun var mı? Bu sorunla daha önce karşılaştı mı?

Answer 1

İhtiyacınız varsa, belirli dosyaları istemek için bir yol yoktur. S3distcp dosyasını tüm dosya yollarını (farklı klasörlerde olsa bile) saklamanızı sağlayan --copyFromManifest seçeneğini kullanabilirsiniz.
