Error creating file on mounted folder : Cannot run program "chmod": error=2

Question

I am trying to copy a file from one folder to another on a mounted folder. I see the following error. Note that this is on mounted NFS folder not on HDFS.The error is coming up from the line of code that does a create() of the destination file. The "No such file" error is not on the source.

java.io.IOException: Cannot run program "chmod": error=2, No such file or direct                                                                                                                     ory

Why would you call a shell program to change mode bits? https://stackoverflow.com/a/664443/1216776 — stark, Aug 11 '20 at 18:18
