Is there any way to use a hdfs file as a Circular buffer?

[Wukang Lin]

Hi all,
   Is there any way to use a hdfs file as a Circular buffer? I mean,
if I set a quotas to a directory on hdfs, and writting data to a file
in that directory continuously. Once the quotas exceeded, I can
redirect the writter and write the data from the beginning of the file
automatically .
