I think the problem here is that he doesn't have Hadoop installed on this other location so there's no Hadoop DFS client to do the put directly into HDFS on, he would normally copy the file to one of the nodes in the cluster where the client files are installed. I've had the same problem recently.
I've tried setting up dfs-hdfs-proxy, though I must say that it's been crashing when I try to put modest to large files through it (but I've got a thread going with the developer on that issue). That, or one of the other remote mount options might work well. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved= 0CDQQFjAA&url=http%3A%2F%2Fwiki.apache.org%2Fhadoop%2FMountableHDFS&ei=T-pwU Y74A8jPrQfYooHoBw&usg=AFQjCNEQbxmrMGKAETj3FPEw3Lr1PBHz-w&sig2=4JpEzZ_8IAyJ-N PofSRmMg&bvm=bv.45373924,d.bmk You could also install Hadoop on the box that has the 2TB file (I realize that you might not control it or want to do that depending on the configuration). A remote NFS mount that you can access from one of the Hadoop boxes... ? Split up the file into smaller pieces? There are some ideas. I'd love to hear your final solution as I've also been having fits getting into HDFS from outside the Hadoop environment. I wish it natively supported NFS mounts or some light weight/easy to install remote DFS tools.

HDFS should be able to consume it just fine, as the client chunks them into fixed size blocks. On Fri, Apr 19, 2013 at 10:05 AM, 超级塞亚人 <shel...@gmail.com> wrote: > I have a problem.
