Did you receive a confirmation message when you sent the unsubscribe
email?  Could you be subscribed on two different email accounts?

Re: FYI: Backports of Hive UDFs

[Alan Gates]

I'm curious why these can't be backported inside Hive.  If someone is
willing to do the work to do the backport we can check them into the Hive 1
branch.

Using org.ietf.jgss.GSSCredential to access Hive Server 2 JDBC

[Nirmal Kumar]

Hi All,

I am having a kerberized HDP 2.5.

I am doing Kerberos SPNEGO authentication from browser(on a client machine 
where I did the kinit and have a valid Kerberos ticket in the ticket cache) and 
able to get the org.ietf.jgss.GSSCredential in my web application (hosted on a 
different node).

FLOW:
---
Hitting the web app URL I get the challenge response header WWW-Authenticate: 
Negotiate and then the browser uses GSS-API to load the user's Kerberos ticket 
from ticket cache of the form Authorization: Negotiate YII. This works 
perfectly fine and I am authenticated via Kerberos and landed up in my web app.

On the web app I get this *org.ietf.jgss.GSSCredential* and now want to figure 
out how this org.ietf.jgss.GSSCredential can be used to access Hive Server2 via 
JDBC (without doing a kinit).

I see code like from Cloudera JDBC Driver for Impala :
jdbc:impala://node1.example.com:21050;AuthMech=1;KrbRealm=EXAMPLE.COM;KrbHostFQDN=node1.example.com;KrbServiceName=impala

https://www.cloudera.com/documentation/other/connectors/impala-jdbc/latest/Cloudera-JDBC-Driver-for-Impala-Install-Guide.pdf

And Simba driver for Impala
--
GSSCredential userCredential = [GSSCredential]
Driver driver = (Driver) 
Class.forName("com.simba.impala.jdbc41.Driver").newInstance();
Properties properties = new Properties();
properties.put("userGSSCredential", userCredential);
Connection conn = 
driver.connect("jdbc:impala://node1.example.com:21050;AuthMech=1;KrbRealm=EXAMPLE.COM;KrbHostFQDN=node1.example.com;KrbServiceName=impala"
 ,properties);

http://www.simba.com/products/Impala/doc/JDBC_InstallGuide/content/jdbc/im/authenticating/delegatedkerberos.htm

Simba driver for Hive
-
jdbc:hive2://node1.example.com:1;AuthMech=1;KrbRealm=EXAMPLE.COM;KrbHostFQDN=hs2node1.example.com;KrbServiceName=hive;KrbAuthType=2

http://www.simba.com/products/Hive/doc/JDBC_InstallGuide/content/jdbc/hi/authenticating/kerberos.htm

I am using HDP 2.5 and hence using the "org.apache.hive.jdbc.HiveDriver".
Not sure if the "org.apache.hive.jdbc.HiveDriver" supports the JDBC Urls that 
somehow allow me to use org.ietf.jgss.GSSCredential.
I did not find any mentions on the Apache Hive docs.

Correct me if I am wrong I am thinking of  ways to pass 
*org.ietf.jgss.GSSCredential* via GSS API calls to access Hive Server 2 jdbc?  
I am not sure about this too.

Any pointers or examples would be of great help here.

Thanks,
-Nirmal

FYI: Backports of Hive UDFs

[Makoto Yui]

Hi,

I created a repository for backporting recent Hive UDFs (as of v2.2.0)
to legacy Hive environment (v0.13.0 or later).

   https://github.com/myui/hive-udf-backports

Hope this helps for those who are using old Hive env :-(

FYI

Makoto
