How is the name length for Hadoop configuration files configured?

The length of Hadoop configuration file names is restricted by the operating system, not controlled by Hadoop itself. Different operating systems have different limitations on file name lengths. For example, Windows restricts file names to 255 characters, while Linux restricts them to 4096 characters. Therefore, when using Hadoop, it is important to adjust file name lengths according to the operating system being used to prevent exceeding its limitations.
