I want to copy 26,000 HDFS files generated by a pig script to Amazon S3.

I am using the copyToLocal command, but I noticed the copy throughput is
only one file per second - so it is going to take about 7 hours to copy all
the files.

The command I am using is: copyToLocal /tmp/files/ s3://my-bucket/

Does anyone have any ideas how I could speed this up?

Thanks,
James

Definitely go down the s3distcp route. I use it to copy large number of
smaller files from s3 into fewer larger ones in HDFS and it's been working
great. This also helps out with the Pig jobs running faster vs. having Pig
try to load XXXX files from s3.

Regards,

Dan

Also use multiple streams of s3 to get better throughput
