13. def getHDFSDefaultBlockSizeMB(fileSystem: FileSystem, path: Option[String] = None): Option[Int]

    

    Returns the default block size of the HDFS filesystem in megabytes.

    Returns the default block size of the HDFS filesystem in megabytes.

    fileSystem

    An HDFS filesystem

    path

    An optional path can be provided if the default block size is path-dependent. The path should not have to exist.

    returns

    A block size in megabytes and None in case of an error
