HBase shell is a JRuby shell and wraps all Java classes in a ruby interface. You can actually use a RandomRowFilter with a 5% configuration to achieve what you need.

Subject: Easiest way to get a random sample of keys
Something like count 't1', {INTERVAL=>20} should give me every 20th row in table 't1'. Is there an easy way to get a random sample via. the shell using filters?
