getFileSize

long getFileSize(org.apache.hadoop.fs.FileSystem fs,
                 String path)
          throws SpaceLimitingException

Computes the size of a single file on the filesystem. If the size cannot be computed for some reason, a SpaceLimitingException is thrown, as the file may violate a quota. If the provided path does not reference a file, an IllegalArgumentException is thrown.

Parameters:

fs - The FileSystem which the path refers to a file upon

path - The path on the fs to a file whose size is being checked

Returns:

The size in bytes of the file

Throws:

SpaceLimitingException
