How to get file size

Question

I am running a hadoop job, I have FileSystem object and Path object and I want to know what is the file (Path) size.

any idea?

Answer 1

long length = FileSystem#getFileStatus(PATH)#getLen();

Here is a link to the relevant documentation of Hadoop 2.2.0

Answer 2

another API is(written in Scala):

    private def getFileSizeByPath(arg : String): Long = {
      val path = new Path(arg)
      val hdfs = path.getFileSystem(new Configuration())
      val cSummary = hdfs.getContentSummary(path)
      val length = cSummary.getLength
      length
    }

Note that the return Long type is Byte in size.
