HBAse connection Issue.

Hi All,

I am encountering some issue to connect from pega to HBase server. I am seeting following error message in the log files. I have imported all the dependent jar files (attached list). Please help us to resolve this if anyone have encountered similar issue.

Thanks,

Sharath.

This is more like a Kerberos configuration related. Can you first verify that a simple java client of HBase works (outside of Pega platform)? This link might be helpful: https://community.cloudera.com/t5/Support-Questions/Kerberos-Failure-to-initialize-security-context/td-p/207512

Hi Kevin,

Thanks for the responce.

When we are initially working on the HBase connection have HBase server version as 1.2.0 cdh5.12.2 and our pega version is 7.3.1. For that we used following dependent jar files (attached doc) .Recently our HBase server version got changed to HBase version 2.1.0 cdh6.2.1 we are still able to connect to HBase server with the same dependent jar files but preview button in the HBase dataset is failed to fetch records from HBase table. For that pega product team provided a hotfix and new dependent jar files (please see the list in the doc attached). After I import these new jar files and Hotfix, I am seeing the issue related to the kerberos (With the old jar files HBase connection is still working).

I feel like we are still missing some depent jar files for the HBase version 2.1.0 cdh6.2.1. please let me know your thoughts.

Thanks
