I have written below program to get TGT using username and password. Mas, quando estou tentando configurar Apache NiFi para acessar Hive ou HDFS Cluster Kerberized Cloudera Hadoop. For more information about Kerberos configuration files, see Kerberos Requirements.
Dbvisualizer pass kerberos cache file driver#
If you can explain the difference between two or point me to a good article which explains both approach in details, that would be really helpful. The following code needs to be in the above kerberos code block to pass kerberos authentication. Beginning in Microsoft JDBC Driver 6.2, name of login module configuration file can optionally be passed using connection property jaasConfigurationName, this allows each connection to have its own login configuration. But limitation with this approach is as mentioned earlier, the max length of TGT(7days), I can't use it for long running jobs, at least that's what I understood(correct me).
Dbvisualizer pass kerberos cache file password#
I am leaning towards cache approach since I can securely keep username and password in keyvault and never have to worry about securing keytab.

Another point from this post is that kinit cache is only good for short running application since we cannot renew TGT beyond 7 days. Here are the steps for using CacheDataSource: Import the java.sql and packages: import java.sql. This post also pointed out that TGT from keytab can be renewed by calling checkTGTAndReloginFromKeytab but it did not talk about renewal process for renewing TGT of kinit cache but I think it can be done using renewTGT property in jaas config(correct me if I am wrong). I did google and found this article which explained how both options works. Login using principal name and password to create TGT in cache andīefore I decide which approach I should take, I want to understand pros and cons of both options. The Database Service will use the keytab file instead of using username/password when interacting with the KDC.

Create a Keytab file and move it to the Database Server. My understanding is I can do it in two ways: Based on the above we can see that a TGT has been placed in the default Kerberos cache.

The secret key inside will be encrypted - that's ok, look at how the SPN is formulated inside the. I am writing a java program to access seured HBase on kerberized cluster. To help resolve what still could be wrong after the above steps, then using Notepad++ (not regular Notepad) right-click and edit your keytab file, simply copy the contents of the keytab file (don't make any changes) and then examine the results.
