kubectl cp device-database-79fc964c8-q7ncc:tmp /Users/raja
error: unexpected EOF
or
kubectl cp device-database-79fc964c8-q7ncc:tmp/plsql_data/prod.dump /Users/raja/prod.dump

kubectl version --client

Can anyone help how to fix this issue?

Using a "cat" command, rather than "cp" worked for me -- but only after 3 attempts.
The "cp" command failed over and over to get the whole file.
This "cat" style command did better each time.
So try this and see if your odds improve!
kubectl exec -i [pod name] -c [container name] -- cat [path to file] > [output file]

It seems to be a bug in Kubernetes, when trying to
cp big files. I assume that's your case. See: github.com/kubernetes/kubernetes/issues/60140marioPermalink

Could you move your db dump to a separate directory and then try to copy the entire directory ? This may look like this:
kubectl cp device-database-79fc964c8-q7ncc:tmp/plsql_data/directory_containing_prod_dump /Users/raja/new_local_dir_containing_db_dump. According to this comment it may help.
