HBase custom filter protocol buffers

[Kevin <ke...@gmail.com>]

Hi,

I'm making the switch from 0.92.1 to 0.98.1, and I'm in the process of
updating all my custom filters to conform to the new HBase Filter API. I
have quite a few custom filters, so my question is: Must I create a custom
protocol buffer for each of my filters or I can reuse the custom logic that
I had in writeFields() and readFields() in toByteArray() and
parseFrom(byte[]), respectively?

I did post this same question on Cloudera's CDH User Google group, but I
figured it was better suited to be asked on the official HBase mailing
list. (Sorry for posting in multiple locations.)

Thanks,
Kevin

For each of your filters that carries custom information (limit, range,
etc), you need to create corresponding protobuf entity.

See hbase-protocol/src/main/protobuf/Filter.proto for examples.

Cheers
