As the referred article too suggests, if you were to attempt recovering accidentally deleted files in Production cluster's HDFS, then it is recommended to immediately stop all the DataNodes in the cluster and seek support's help to go through the process.

When it is about recovering production data, it is very important that one has very clear understanding of the recovery procedure, knows all the precautions and checks to be taken care of and is confident on how to proceed if any of the steps fail.
