Is it possible to connect to Hive via beeline using kerberos keytab file similar to the approach used for JDBC at. PS : beeline does support connecting on a kerberos secured hive server with username and password. But I am looking for a way to connect it with a keytab file. I think you cannot connect with keytab file into beeline but you can get ticket with keytab using kinit and then pass the hive server principal with the jdbc connection string of beeline to connect.

Though you provided kerberos detailsstill it will ask you the username and password. Learn more. Asked 4 years, 9 months ago.

The second link, which you've pasted, shows how to do that. Path to keytab file should be passed in the hive-site. Afterwards you connect by command:!

But even after attempting with the above connection string, it still asks for the username and password. Am I missing something? Just press enter two times. No need to enter any username and password.

Cloudera is using Sentry for fine grained authorization of data and metadata stored on a Hadoop cluster. This blog is related to the hive command-line toolusing Hive through HUE is fine! The primary difference between the two involves how the clients connect to Hive.

However, Beeline connects to HiveServer2 and does not require the installation of Hive libraries on the same machine as the client. Beeline is a thin client that also uses the Hive JDBC driver but instead executes queries through HiveServer2, which allows multiple concurrent client connections and supports authentication. So hive though the command-line will not follow the policy from Setry. Use beeline or impala-sell instead.

For a non secured cluster it is easy to connect. You can use beeline as described in this blog cloudera-migrating-hive-to-beeline. More info on the beeline-command-options and hive-command-options on the apache wiki. All the errors look the same. Error: Invalid URL When you run into problems, check the hiveserver2 logs for hints.

Note that the Invalid URL message does not contain the principle part! Use "quotes around the url"otherwise the hive principle argument is not used. There is a keytab-file on the HiveServer2-node initialized with the principle. The connection string is using the wrong Kerberos principle for the keytab-file. Make sure you provide the correct hive principle in the connection url.

The second part is special to Kerberos. It tells you what service principal is used to authenticate to this URL. This is required so that beeline knows what specific kerberos TGT to look for. All of this assumes that when you login to the edge node server, you followed standard protocol to get a kerberos TGT. The profile is setup so that you're automatically prompted again for your password. This establishes your TGT. Margus Roo are you still having issues with this? Can you accept best answer or provide your own solution?

I do not know is it solution here but one helpful think is to enable kerberos debug mode to see what kerberos wants:. View solution in original post. Hi Margus, I am facing similar issue and setting the debug flag is not helping me much.

I tried all the various ways of login to beeline, with and without hive services tickets and also with different TGTs. Would you see any other check I might need to do here? Was your issue based on similar lines? Would you mind sharing the fix you made for the problem. The issue with beeline access to hive when using Kerberos, is that we need to use the "right principal" in the connection string - and it MUST be hive's principal. So you must explicitly do a kinit and grab a valid ticket from Kerberos.

We do not have issues with knit on Linux hosts. Not sure how to test 'kinit' - like behavior on Windows. We got this working. Place the krb5. After debugging for hours, and checking traces and more, this is wall it took. I am not sure where Windows stores it's tickets, if even in a readable form. There must be a way to use the tickets Windows has. It must be doable. But maybe it should there.

Please create separate feature request. Probably there are some existing Eclipse plugins which will simplify the task. I am wondering why kint. Is it used somehow? For now, we wrote a powershell script via a "Before Connect" shell sequence. This will prompt the user with kinit.

Used only if HA mode for HiveServer2 is enabled. Defaults to in binary mode. Defaults to in HTTP transport mode.Beeline is a Hive client that is included on the head nodes of your HDInsight cluster. To install Beeline locally, see Install beeline clientbelow. The following examples provide the most common connection strings used to connect to HDInsight from Beeline. When connecting from an SSH session to a cluster headnode, you can then connect to the headnodehost address on port :.

Since this connection is made directly to the cluster nodes, the connection uses port :. Ensure that HiveServer2 is running. When connecting to a cluster using the public or private endpoints, you must provide the cluster login account name default admin and password.

For example, using Beeline from a client system to connect to the clustername. Replace clustername with the name of your HDInsight cluster. Replace admin with the cluster login account for your cluster. Replace password with the password for the cluster login account. Private endpoints point to a basic load balancer, which can only be accessed from the VNETs peered in the same region. See constraints on global VNet peering and load balancers for more info. You can use the curl command with -v option to troubleshoot any connectivity problems with public or private endpoints before using beeline.

Apache Spark provides its own implementation of HiveServer2, which is sometimes referred to as the Spark Thrift server. This service uses Spark SQL to resolve queries instead of Hive, and may provide better performance depending on your query.

The connection string used is slightly different. When connecting directly from the cluster head node, or from a resource inside the same Azure Virtual Network as the HDInsight cluster, port should be used for Spark Thrift server instead of The following example shows how to connect directly to the head node:.

A Hadoop cluster on HDInsight. Notice the URI scheme for your cluster's primary storage. For more information, see secure transfer. Option 1: An SSH client.
