Hi,
Is there any lock service in hadoop to sync the access to file (such
as chubby in GFS)?

Thanks

    There is somewhat less need for this at this point since files appear
    atomically and cannot be modified (even for append).

    There are rumors of impending appendability.

    Currently no. Yahoo is planning on releasing one soon (2-3 weeks).
