How connect to Hive with Squirrel and beeline command - hive

If I enter the remote machine dlw2nia-bd01, and I execute beeline and I execute this connecting string
!connect jdbc:hive2://dlw2nia-bd02.walgreens.com:2181,dlw2nia-bd03.walgreens.com:2181,dlw2nia-bd10.walgreens.com:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2
, I can connect to Hive, in fact I see:
Connected to: Apache Hive (version 1.2.1000.2.6.4.0-91)
Driver: Hive JDBC (version 1.2.1000.2.6.4.0-91)
Transaction isolation: TRANSACTION_REPEATABLE_READ
0: jdbc:hive2://dlw2nia-bd02.walgreens.com:21>
I would like to use, however, a client to better show the Hive tables.
I installed JDBC Driver Clouder and I tried to configure Squirrel to connect to Hive but I'm having an issue connection. Another SQL Client such as DBEaver or SQlDeveloper would also be fine.
I was thinking of downloading the drivers JDBC used for Beeline and using them with an SQL client, but I don't know where to find drivers in the remote machine.
Can you help me configure a client to connect to Hive?

connecting to hive to execute queries wih kerberos

I am trying to connect to hive databases with a client, I have tried using DBeaver and downloaded the hive driver, but after that I have noticed that there is a kerbero's instance in the middle, and it seems that the dbeaver driver doesn't supoort kerberos.
¿There is some windows client suitable to query hive databases easy to plug in, considering the kerbero's instance?
Thanks in advance.

How to configure hive-site.xml for ODBC connection

I have configured an ODBC connection in Windows ODBC Data Source Administrator and test successfully.
I want to connect to HIVE database (the ODBC connection) using Spark. As my understanding, the connection should be configured in hive-site.xml and put to folder /config. But how to configure hive-site.xml using ODBC connection? Can anyone provide an example for hive-site.xml?
I am using cloudera ODBC driver.
Environment: Windows, spark 2.3.3

Can not connect to Spark Thrift Server using JDBC, keeps using Hive

I am using Azure HDInsight and want to connect to Thrift Server using JDBC in similar way as described here: Thrift JDBC/ODBC Server.
However it always connects to Hive and not Spark Thrift Server. While they both look similar and I can query data, I want to exploit Spark execution engine as I am using mainly Spark2 and sometimes need JDBC connection. Spark engine is also probably faster than Hive/TEZ.  
Connection string looks like this:
jdbc:hive2://hdinsight-name.azurehdinsight.net:443/default;ssl=true?hive.server2.transport.mode=http;hive.server2.thrift.http.path=/hive2
Drivers tried:
1. maven:/org.spark-project.hive:hive-jdbc:1.2.1.spark2
2. maven:/org.apache.hive:hive-jdbc
Update: Looks like Spark Thrift Server is not exposed to public: Ports used in HDInsight
I was able to connect to Spark Thrift Server from JDBC client with following workaround.
Spark Thrift Server is running on port 10002, which is not publicly accessible as documented here in Azure HDInsight docs. Thus, here is alternative way to connect to Spark SQL from local JDBC client.
Background:
I connected to cluster head node via SSH.
ssh user#cluster-name-ssh.azurehdinsight.net
From here, I was able to connect to Spark Thrift Server using Beeline client.
beeline -u 'jdbc:hive2://localhost:10002/;transportMode=http'
With Beeline, I can run SQL queries using Spark engine.
Solution:
So I set up SSH port forwarding in my local machine (forward local port 10002 to cluster head node)
ssh -L 10002:localhost:10002 user#cluster-name-ssh.azurehdinsight.net
Now, I can use this port in JDBC client to connect to Spark SQL.
jdbc:hive2://localhost:10002/;transportMode=http
With that, you can use Spark SQL from your local JDBC client.

Differences between beeline embedded and remote modes?

What are the real differences between beeline embedded and remote modes? Do they just refer to connecting to remote hive server versus local hive server? When we connect to beeline through embedded mode does the client run in the same JVM of hive?

Cannot query Hive remote server

I am trying to query on remote hive server2. The connection was successful but I am not able to query.
The screen freezes for long time.
I am not sure the query request went to hive server.
Here I started Hive server2 and trying to connect through HIVE CLI
Actually HIVE CLI is for hiveserver1,
Beeline is correct one for hiveserver2
