将hbase streamreactor kafka连接器用于此配置的

name=person-hbase 
connector.class=com.datamountaineer.streamreactor.connect.hbase.HbaseSinkConnector 
tasks.max=1 
topics=hbase-topic
connect.hbase.column.family=d
connect.hbase.kcql=INSERT INTO person SELECT * FROM hbase-topic PK firstName, lastName

为什么Kafka向hbase发送的值用这种方式表示？ value=@\xB56\x00\x00\x00\x00\x00 如何把它改成正常的可读方式？

hbase(main):004:0* scan 'person'
