chunhui shen commented on HBASE-8865:
-------------------------------------

I think the patch should be ok, 
it won't break string rowkeys unless considering '\x' as a string rather than 
tag of hex digits.

In the real application, '\x' is more able to be considered as a tag of hex 
digits

if only choose one, I prefere to use 'toBytesBinary'.

Making two methods to support two scenarios should also be ok.

> When I tried to do a manual region split from HBase shell, I found that split 
> command acts incorrectly with hex split keys. 
> Here is an example.
> I execute hbase(main):003:0> split 'tsdb', "\x00\x00\xC3" .
> While I expect it to split at the 3-byte key "\x00\x00\xC3" , it actually 
> split at a 5-byte key "\x00\x00\xEF\xBF\xBD". 
> I test with more split keys and find some patterns:
> * If the all bytes in the split key represented in hexadecimal are between 
> "\x00" and "\x7F" , it works as expected and split at exactly the key 
> specified.
> * If there are any bytes between "\x80" and "xFF", it works incorrectly. No 
> matter the byte is, it is interpreted as "\xEF\xBF\xBD". Here is another 
> example. Specifying split key "\x00\xA0\x00\xB0" actually splits at 
> "\x00\xEF\xBF\xBD\x00\xEF\xBF\xBD".
> I'm running Hbase 0.94.8, r1485407, both server-side and client-side.
