Getting error when copying file from s3:// to local(hadoop) file system

Question

I am trying to copy the files from s3 to hadoop file system using python. I got the following error:

cp: `foo/ds=2015-02-13/ip-d1b-request-2015-02-13_10-00_10-09.txt.gz': No such file or directory

I am recently migrating latest hadoop version(2.4.0). In version(0.20) is working fine. Why I m getting this error in the 2.4.0 version?

In Hadoop version 0.20

hadoop@ip-10-76-38-167:~$ /home/hadoop/bin/hadoop fs -cp s3://test.com/foo/ds=2015-02-13/ip-d1b-request-2015-02-13_10-00_10-09.txt.gz /foo/ds=2015-02-13/ip-d1b-request-2015-02-13_10-00_10-09.txt.gz

Answer 1

You need to try like this . Add "

/home/hadoop/bin/hadoop fs -cp "s3://test.com/foo/ds=2015-02-13/ip-d1b-request-2015-02-13_10-00_10-09.txt.gz" "/foo/ds=2015-02-13/ip-d1b-request-2015-02-13_10-00_10-09.txt.gz"

Answer 2

I found the answer my own.

Using `distcp` instead of `fs -cp`.

This command works without any issues.
