[jira] [Commented] (HBASE-21178) [BC break] : Get and Scan operation with a custom converter_class not working

["Sean Busbey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-21178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16721598#comment-16721598 ] 

Sean Busbey commented on HBASE-21178:
-------------------------------------

Can we get a release note for this please? It's fixing a critical shortfall that users upgrading to 2.y need to be aware of.

 

I've also filed HBASE-21605 for a related documentation change so that folks considering upgrade can be made aware.

> 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)]
