Ted Yu commented on HBASE-21178:
--------------------------------
{code}
782 converter_class = 'org.apache.hadoop.hbase.util.Bytes' unless
converter_class
783 converter_method = 'toStringBinary' unless converter_method
784 eval(converter_class).method(converter_method).call(bytes)
{code}
Is it possible that one of converter_class / converter_method is null ?
In that case the conversion should be skipped, right ?
Also, is it possible to add a test with conversion to prevent regression ?
Thanks for the finding.

> Project: HBase
> Issue Type: Bug

> 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)]
