Re: Can I use the Thrift API to scan with filters?

Hi

Thanks for the quick replies.

I've tried to apply the filters but I get in the Thrift server log screen:

SingleColumnValueFilter('familycolumn', 'column', =, 'value') = Invalid
comparator
SingleColumnValueFilter('familycolumn', 'column', EQUAL, 'value') =
Invalid comparator
SingleColumnValueFilter('familycolumn', 'column', 'EQUAL', 'value') =
Invalid comparator
SingleColumnValueFilter('familycolumn', 'column',
CompareFilter::CompareOp.valueOf('EQUAL'), 'value') = Expected 4 or 6 but
got: 3
SingleColumnValueFilter(Bytes.toBytes('familycolumn'),
Bytes.toBytes('column'), CompareFilter::CompareOp.valueOf('EQUAL'),
Bytes.toBytes('value')) = Expected 4 or 6 but got: 1

I couldn't find on the Internet an example of a SingleColumnValueFilter
with the Thrift Java API.

Regards,

Néstor
