Couldn't establish Hive DB session in nodejs

[#1]

Hi Team,

Good Day..

I'm beginner in Node.JS trying to connect Hive DB  using

hive-driver npm from Node.JS code.

I couldn't establish the db connection.

Any help would be much appreciated...

Note: Our Hive DB has ssl connection, jks trust store password, HTTP protocol , httppath=cliservice

NODE.JS  SAMPLE CODE:

client.connect(
{
host: 'jdbc:hive2://abc.com:2181/dev_db;ssl=true;sslTrustStore=/etc/hive-jks/hivetrust.jks;trustStorePassword=pro@!23;transportMode=http;httpPath=cliservice;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2',
port: 2181
},
new hive.connections.HttpConnection(),
new hive.auth.PlainHttpAuthentication({
username: 'username',
password: 'password'
})
).then(async client => {

console.log(client);

const session = await client.openSession({
client_protocol: TCLIService_types.TProtocolVersion.HIVE_CLI_SERVICE_PROTOCOL_V10
});

}).catch(error => {
console.log(error);
});

when I console.log client It's printing but I tried to open client.open session I've been facing issues 

Kindly check the host url string  which I've given right or not.

Could you please help on this issue.

PFB Error.

Thank you..

@Viki_Nodejs It seems like the hostname resolution fails. The url you have shared is rather jdbc compliant. 

Could you give the following a try?

client.connect(
  {
    host: 'abc.com',
    port: 2181
  },
  new hive.connections.HttpConnection({
    transportMode: 'http', 
    httpPath: 'cliservice',
    serviceDiscoveryMode: 'zooKeeper', 
    zooKeeperNamespace: 'hiveserver2'
  }),
  new hive.auth.PlainHttpAuthentication({
    username: 'username',
    password: 'password'
  }),
  {
    ssl: true,
    sslTrustStore: '/etc/hive-jks/hivetrust.jks',
    trustStorePassword: 'pro@!23'
  }
).then(async client => {

Hi Smruti,

Thanks for your reply. I've used the above snippet. PFB Error

Do we get this error after it gets connected? Could there be a socket timeout error set at client side? I am not aware if the hive driver has a default timeout value. 
Instead of ZooKeeper, could you try connecting to HS2 directly.
e.g.
host: "hs2 node fqdn"
port: 10001

Remove
serviceDiscoveryMode: 'zooKeeper',
zooKeeperNamespace: 'hiveserver2'
