Description

Consider a simple scenario:

create 'foo', {NAME => 'f1'}
put 'foo','r1','f1:a',1000
get 'foo','r1',{COLUMNS => ['f1:a:c(org.apache.hadoop.hbase.util.Bytes).len']} 
scan 'foo',{COLUMNS => ['f1:a:c(org.apache.hadoop.hbase.util.Bytes).len']}

Both get and scan fails with ERROR

ERROR: wrong number of arguments (3 for 1) 

Looks like in table.rb file converter_method expects 3 arguments [(bytes, offset, len)] since version 2.0.0, prior to version 2.0.0 it was taking only 1 argument [(bytes)]
