Method from org.apache.hadoop.fs.Seekable Summary:
getPos, seek, seekToNewSource

Method from org.apache.hadoop.fs.Seekable Detail:
public long getPos() throws IOException Return the current offset from the start of the file
public void seek(long pos) throws IOException Seek to the given offset from the start of the file. The next read() will be from that location. Can't seek past the end of the file.
