How to copy files from HDFS to remote server

How to copy files from HDFS to remote server

New Contributor

Hi,

 

I am trying to copy files from HDFS location to a folder in the remote server.

 

I have tried using hdfs dfs -get/-copyToLocal <hdfs path> <local path> commands, yet no luck.

 

I need to make this script run automatically everyday. How do i do that?

 

I am very new to Hadoop. Any help is greatly appreciated

Can you not install hdfs client (just binaries) on the remote server and run a cron job to get hdfs data you want locally? That way you don't need to cache data locally and then rsync/scp to remote server?

Hi @Naush007 When you say remote server you mean a different host in the same network but on different cluster ? -copyToLocal is just for the same host on which you have the data. It will not copy to a different host. To do this you can use "DistCp" Distributed Copy tool to copy the data you want. Refer to below links for more information and how to use them.
