hdfs remote copy timeout

Whenever my Hadoop cluster is under heavy load, I can't copy a file from
HDFS (using hdfs -copyToLocal) to my desktop. Is there anything that I can
tune in DataNode to avoid socket time out?

Hi Kiet

You can try increasing the timeout using the configuration 
dfs.client.socket-timeout
The default is 60000 milliseconds, can increase accordingly.

Thanks
