minor correction in getting started guide

[Shiraz Memon]

Hi,

I found one mistake (although very minor) in MyClient.java class which is
given as an example test case for beginners in getting started page. I
suggest to replace the following line

*new String(columns.get("myColumnFamily:columnQualifier1")));*

with

*new String((byte[])columns.get("myColumnFamily:columnQualifier1")));*


Cheers,

Shiraz
