Hi All,

 

I saw one performance parameter in HDFS & YARN which is named as " Maximum Process File Descriptor" . Does anyone explain me what is that property and why it is used.

 

Thanks

It controls the ulimit for maximum file descriptors for the given process. There's one version of this property for each daemon role. The operating system enforces that each process doesn't have more open files than the configured limit.
