Ankur commented on HADOOP-1824:
-------------------------------
Ok, But I should be able to change the offset to the end of the stream since
central directory structure of zip file is at the end.
Presently the FSDataInputStream.seek() throws IOExeption and doe not change the
stream position if I try to position it past the
end of stream which is unlike fseek() which positions the offset to end of
stream.
Is there a workaround to this or is it a functionality that needs to be added ?

> HDFS is inefficient with large numbers of small files. Thus one might pack
> many small files into large, compressed, archives. But, for efficient
> map-reduce operation, it is desireable to be able to split inputs into
> smaller chunks, with one or more small original file per split. The zip
> format, unlike tar, permits enumeration of files in the archive without
> scanning the entire archive. Thus a zip InputFormat could efficiently permit
> splitting large archives into splits that contain one or more archived files.
