DaeMyung Kang commented on TAJO-495:
------------------------------------

[~sirpkt] 
I just think SHA-1 is also popular hash function like md5.
so I might think it is better to use "sha1" function directly.

but I think your opinion makes sense.
so I make new issue to support digest also.
(https://issues.apache.org/jira/browse/TAJO-498)

what do you think about this?
