Cannot connect Phoenix to HBase in secure cluster (Kerberos)

Hi,



We are trying to connect to HBase in secure cluster using the following command as mentioned in the website,

./sqlline.py &lt;Zookeeper_Node_Hostname&gt;:5181:/hbase:&lt;Principal&gt;:&lt;keytab&gt;.



Hadoop version is MapR 5.2, HBase ver. 1.1.1 and Phoenix ver. 4.8.1 for HBase 1.1.1.



We have executed "kinit -kt &lt;keytab&gt; &lt;principal&gt;" command on all nodes before starting Phoenix but even then we are not able to connect. Following is the error log displayed,



ERROR:

Phoenix uses log4j to print out log messages to the console. You can
modify the log level in the referenced logj4.properties...

Re: Cannot connect Phoenix to HBase in secure cluster (Kerberos)

Hi,



We did not find any other logs. We have added "-Dsun.security.krb5.debug=true", even then there is no much information about the error. 

And also there are no logs about Phoenix trying to perform kerberos authentication in HBase logs as well as in Kerberos logs. The log shared in the earlier mail is the only information on error we have got.





Thanks &amp; Regards,

Rohit R. K.

When you provide the principal and keytab options in the JDBC URL, the 

ticket cache (created by your kinit invocation) is not used. 

 

What does the other logging say from your client? You should see a 

message about Phoenix performing a Kerberos login given the information 

you provided.
