Closing connections

[misterdai]

I can't seem to have the HBase client close all connections and all the Node.js process to exit normally. I've tried iterating the client.servers and calling .close() against each of them but I just receive a message about the connection being closed with no error and the Node.js process stays open (no other code is contained).

Exampe:

var HBase = require('hbase-client');
var client = HBase.create({zookeeperHosts: ['127.0.0.1:2181']});

client.getRow('table', 'rowName', ['field'], function(err, row) {
  console.log(row);
  // How do I close the connection?
  for (var name in client.servers) {
    console.log('Closing connection to ' + name + '.');
    client.servers[name].close();
  }
});

This script, doesn't ever finish executing for me.

Looking further into this, it appears that the Zookeeper client is still keeping the connection open. The following will work...

var HBase = require('hbase-client');
var client = HBase.create({zookeeperHosts: ['127.0.0.1:2181']});

client.getRow('table', 'rowName', ['field'], function(err, row) {
  console.log(row);
  // Closing the connection(s)
  for (var name in client.servers) {
    console.log('Closing connection to ' + name + '.');
    client.servers[name].close();
  }
  client.zk.close();
});

However, I'd like to suggest that this be incorporated into this module rather than having to perform it manually. For example client.close([callback]) could close all the server connections and the Zookeeper connection, finally calling an optional callback when complete.
