Why do you want to use TikaInputStream like this?

Thanks Zukka for your reply.

Can u pls tell me how to use the beforeRead() method in TikaInputStream to
set readlimit for reading bytes from a stream.

You can use the BoundedInputStream [1] class from Commons IO:

    TikaInputStream.get(new BoundedInputStream(stream, 1000));

However, see the concern in TIKA-307 [2]. Passing a truncated stream
to Tika may produce unexpected results.
