HBASE-2400 introduced a new connector contrib architecturally equivalent to the Thrift connector, but using Avro serialization and associated transport and RPC server work. However, it remains unfinished, was developed against an old version of Avro, is currently not maintained, and is regarded as "not production quality" (see: http://www.quora.com/What-is-the-current-status-for-using-Avro-with-HBase). Therefore I propose:
If a contributor steps up, then this person should bring the Avro connector up to par with the Thrift connector. Otherwise, we should deprecate and remove the Avro connector. Best regards, - Andy Problems worthy of attack prove their worth by hitting back. - Piet Hein (via Tom White)
