Hi,
I understand from your answer that it's possible but not available.
Did anyone already implemented such a functionality?
If not, where should I begin to look at (hirb.rb, any tutorial,... ?) -
I know nothing about jruby.
Tks,

(For 2) I think the hash function should work in the shell if it
returns a string type (like what '' defines in-place).

Hi,
To help avoid hotspots, I'm planning to use hashed keys in some tables.
1. I wonder if this strategy is adviced for range queries (from/to key) use
case, because the rows will be randomly distributed in different regions.
Will it cause some performance loose?
2. Is it possible to query from hbase shell with something like "get 't1',
@hash('r1')", to let the shell compute the hash for you from the readable
key.
3. There are MD5 and Jenkins classes in hbase.util package. What would you
advice? what about SHA1?
Tks,

PS: I searched the archive but didn't find the answers.
