Step-1: First make sure you can get a kerberos ticket using kinit on linux terminal and you have a Kerberos principal that can access Hive tables. The Microsoft JDBC Driver for SQL Server allows an application to use the authenticationScheme connection property to indicate that it wants to connect to a database using NTLM v2 Authentication. Any one know something about Kerberos Delegation in SAP HANA DB via jdbc? This post will help you connect a JDBC client to Hive server using Kerberos Keytab for authentication. Note: The JDBC Driver from Oracle previous 11.0.2 had bug with kerberos authentication, so you need to get latest one (alas I could not make work with Oracle 12c ojdbc7.jar either) Edit the standalone.xml, could be standalone-teiid.xml depending upon how you installed Teiid, and add the following The wrapped JDBC driver and the SQL Server driver need to be on the classpath of the driver and executors. Defines the additional Java Class directories or full-path jar names which will be available for Java Services. With Microsoft SQL Server JDBC driver, you can connect to the database through SQL Server Authentication or Kerberos Authentication. High performance connection pooling is also provided. I have properly configured SAP HANA for Single Sign-On using kerberos authentication. The simplest way to connect using Kerberos is to generate a TGT on the client side. Setting Up a Hive Connection with Kerberos using Apache JDBC Drivers (Windows) Follow. Before going forward, let's get agreed with the initial information used in configuration files. High performance connection pooling is also . You can do this via the "-keytab" and "-principal" flags during your Spark Submit. The following example instantiates a Java properties object, uses it to set each of the parameters in Table 9-3, and then uses the properties object in opening a connection to the . Now same i want to connect with jdbc java client. Kerberos authentication is another option to connect to Hive. This JDBC Connection tutorial explains basic steps to a database with examples and provides JDBC connection strings for different databases: In the previous tutorial of the JDBC tutorial series, we learned components, architecture, and types of drivers in Java Database Connectivity (JDBC).. Thanks @dvillarreal and @Abdelkrim Hadjidj, it turned out that using a gss-jaas.conf file does work to auto-login from keytab, I just had to make sure to also set. When connecting to a JDBC data source using Kerberos authentication, you can sometimes face a problem if the Kerberos tickets have a finite lifetime. You can look at the example for basic JDBC authentication using SQL Server. The following properties are also used for NTLM Authentication: domain = domainName (optional) user = userName. Types of authentications' methods supported are SIMPLE, and KERBEROS: zeppelin.jdbc.principal: The principal name to load from the keytab: zeppelin.jdbc.keytab.location: The path to the keytab file: zeppelin.jdbc.auth.kerberos.proxy.enable: When auth type is Kerberos, enable/disable Kerberos proxy with the login user to get the connection. Impala 2.0 and later are compatible with the Hive 0.13 driver. in the startup options of the ETL tool. hivejdbc. Hadoop cluster that I was connecting to was Kerberised, which made the exercise more tricky. I can not use Kerberos Delegation. Introduction. Solution. Create a JDBC Login Context. You need to set allowTgtSessionKey to 1 in the registry for Windows. 5.2. The attached JAR file can be used to test connectivity to Hive Database, which is Kerberos enabled. For example, to specify properties using the Properties interface, use the following code as an example .

OrientDB Kerberos Client Examples. You can start setting up kerberos on your windows machine. Hive JDBC Connection Examples. The idea was to use Java locally (in my case with InteliJ) to connect to Hive metastore through Impala. The following article describes how to set up a kerberized connection to Oracle for QuerySurge Agents deployed on Linux. JDBC has evolved since that time from a thin API on top of an ODBC . It can be accomplished by adding a new driver to DBeaver. //Java 8 to 11 compile "com.zaxxer:HikariCP:3.4.1" //java 7 compile "com.zaxxer:HikariCP-java7:2.4.13" //Java 6 compile "com.zaxxer:HikariCP-java6:2.3.13" Creating JDBC Connection Pool with HikariCP While Creating the HikariCP DataSource object, an interface for Connection Pool provided by Java, we need to configure the pool. This tutorial explains JDBC transaction types, data types, transaction management methods, and how to use them in Java program: In the JDBC ResultSet tutorial of the JDBC tutorial series, we learned to use JDBC ResultSet to retrieve data. 1. We have seen a brief introduction to the . While there are posts already existing for JDBC connectivity to Hive using kerberos username and raw password (like this), but I did not find anything addressing the use of Keytab.In addition we make use of Subjects which is the most comfortable abstraction for user . 2) For HOW TO, enter the procedure in steps. Also, it's worth mentioning that if you use kerberos, I did have some issues with differing java versions. For example, if downloading the 7.2.2.0 version of the driver, find either of the following: We strongly encourage using the specific Apache drivers from your Hadoop distro and version.

The Trino JDBC driver allows users to access Trino using Java-based applications, and other non-Java applications running in a JVM. You don't need to specify username or password for creating connection when using Kerberos. JDBC Driver openLooKeng can be accessed from Java using the JDBC driver. Here I am going to use "HTTP/[email protected]" user as Service Provider Principle.I could also have used the SPN "krbtgt/[email protected]".In Kerberos, there are three systems, one is client user (that is you, ex:rareddy), second is where the service you want to access (that is Teiid server), and then the kerberos server itself. 4.3. Both desktop and server-side applications, such as those used for reporting and database development, use the JDBC driver. But since our data sources are secured via Kerberos, we cannot "simply" establish a JDBC connection and we need to configure Kerberos on our laptop as well. hivejdbc can use a dictonary cursor if desired.. from hivejdbc import connect, DictCursor conn = connect ('example.com', 'default', cursor = DictCursor) Cursors support with If this is the case, you need to change the connection property spotfire.kerberos.refresh.tgt from the default false to true in the data source template.
