Subject Re: Iteration in ResultScanner
Date Wed, 20 Jan 2016 06:32:14 GMT
Hi,

 I want to get all the column values for a given row-key.

Row-key     col1     col2 col3 col4 col5

id100          XXX    YY    ZZZ   AAA   BBB

is there any option available to get all the column values for given
row-key. Here for id100 I want to have XX,YY, ZZZ ,AAA,BBB

Thanks
