Impala ODBC error with Power BI, though Kerberos

New Contributor

Hello guys,

 

I installed Cloudera ODBC Impala 64 driver and set it up on System DSN mode, in order to enable a connection between Impala and Power BI through Kerberos. So far so good, I was able to access my cluster and import individual tables to build my dashboard.

 

However when refreshing my dashboard (this performs a simultaneously import from the selected tables), I found the following error:

 

OLE DB or ODBC error: [DataSource.Error] ODBC: ERROR [HY000] [Cloudera] [KerberosSuport] (0) Error occurred during Kerberos library operation: Internal credentials cache error.

 

I have tried a couple of things based on google research, but so far have gotten no luck on that error message.

Could someone please help me?

Hi;   I have the same issue with our PowerBI reports as well.   We are using the 'Cludera ODBC Driver for Impala v2.06.05.1005; PowerBI May 2020 version; and Impala v3.2x / CDH 6.3.3.

ERROR [HY000] [Cloudera][KerberosSupport] (0) Error occurred during Kerberos library operation: Internal credentials cache error. The exception was raised by the IDbCommand interface.

 

I'm also seeing sporadic "Unexpected response" exceptions...
