Anoop Sam John commented on HBASE-21178:
----------------------------------------
bq.Some of the users have written custom converter classes which started
failing after the upgrade because of the change in method signature.
That explains it.. So I believe the issue is when the custom class name /method
name is been passed.. This is a good find.Which version break it? U know which
jira ? This is a major issue then as it is a BC break!
> Get and Scan operation with converter_class not working

> Consider a simple scenario:
> {code:java}
> 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']}{code}
> Both get and scan fails with ERROR
> {code:java}
> ERROR: wrong number of arguments (3 for 1) {code}
> 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)]
