isValidName

public boolean isValidName(String src)

Description copied from class: AbstractFileSystem

Returns true if the specified string is considered valid in the path part of a URI by this file system. The default implementation enforces the rules of HDFS, but subclasses may override this method to implement specific validation rules for specific file systems.
