scanner not get nothing, but only one cell value , not a whole row , and not any cf or qualifier, only cell!

[#9]

Set Accept header to text/xml for XML encoding , But result like from "application/octet-stream for binary encoding" setting.

I get it !

curl -v -H "Content-Type: text/xml" http://10.148.10.2:9090/device_day_metric_kt/scanner/145589362659469f85bc0

should be

curl -v -H "Accept: application/json" http://10.148.10.2:9090/device_day_metric_kt/scanner/145589362659469f85bc0
