Hadoop WebHDFS move file Could not resolve host: sandbox.hortonworks.com -


so, learn hadoop. use hortonworks sandbox. tried move file local pc (test.txt) hadoop using webhdfs.

to that, found out apache hadoop documentation says need 2 steps. first sumbit put http request, , datanode information.

this do:

curl -i -x put "http://127.0.0.1:50070/webhdfs/v1/user/root/learnhadoop/data/test.txt?user.name=root&op=create"

this response

http/1.1 307 temporary_redirect cache-control: no-cache expires: wed, 01 apr 2015 17:26:10 gmt date: wed, 01 apr 2015 17:26:10 gmt pragma: no-cache expires: wed, 01 apr 2015 17:26:10 gmt date: wed, 01 apr 2015 17:26:10 gmt pragma: no-cache set-cookie: hadoop.auth=u=root&p=root&t=simple&e=1427945170842&s=ey5zvguyx8wryvnr2nbilug14s0=; path=/; expires=thu, 02-apr-2015 03:26:10 gmt; httponly location: http://sandbox.hortonworks.com:50075/webhdfs/v1/user/root/learnhadoop/data/test.txt?op=create&user.name=root&namenoderpcaddress=sandbox.hortonworks.com:8020&overwrite=false content-type: application/octet-stream content-length: 0 server: jetty(6.1.26)

then submit put http request using datanode url.

curl -i -x put -t test.txt "http://sandbox.hortonworks.com:8020/webhdfs/v1/user/root/learnhadoop/data/test.txt?user.name=root&op=create"

after that, nothings happen , error showing up. error message:

curl: (6) not resolve host: sandbox.hortonworks.com

do miss something? should move file hadoop. in advance

as mentioned in comment, temporary fix replace sandbox.hortonworks.com 127.0.0.1 @ places. eventually, guess reason why namenode replys datanode location sandbox.hortonworks.com because vm set hostname sandbox.hortonworks.com, can change hostname localhost resolve problem completely.
