console.log("row");
console.log(row);
console.log("err");

});

any idea ? thanks

Current hbase-client only support 0.94.x, 0.95+ you need to use this https://github.com/falsecz/node-hbase.

I had a similar problem, after analyzing the Hbase log I foudn the following message:

not start ZK at requested port of 2181. ZK was started at port: 2182.

I specified an incorrect port number, once I changed it from 2181 to 2182 it resolved the issue.

var client = hbase.create({ zookeeperHosts: [ '0.0.0.0:2182', ], zookeeperRoot: "HBASE_ROOT_DIRECTORY,
});
