Issue in Distcp from S3 to HDFS
Stuti Awasthi 2012-08-22, 12:45
Hi,

I want to copy data from S3 to Hadoop set up on EC2 instances. To attain this I configured AWS keys in Hadoop configuration file and able to copy file from S3 to HDFS. But getting error if I want to copy the complete folder hierarchy to HDFS.

Command I used :

bin/hadoop distcp s3n://MyBucket/MyFolder/ hdfs://Hostname:Port/test/OUTPUT/

org.apache.hadoop.tools.DistCp$DuplicationException: Invalid input, there are duplicated files in the sources: s3n://MyBucket/MyFolder/Hello, s3n://MyBucket/MyFolder/Hello
