*In /etc/security/limits.conf change the per user or the system default number of open files
adding this line * hard nofile 65536 will allow any user to open up 65536 files*. I realized that this could be one alternative. But what if the process writing to HDFS is a daemon that's designed to run 24X7? In that scenario, will it eventually, over time, use all the open files? Or will the DFSClient periodically close resources that it no longer needs? Thanks again.
