Impala - Failed to update data source credentials
This is the error I got trying to refresh data from Impala.
Failed to update data source credentials: ODBC: ERROR [HY000] [Microsoft][ThriftExtension] (0) Failed to initialize SASL client library: generic failureHide details
Connection by Desktop works but the problem is with refreshing data from Service.
Doesn’t work on both personal or enterprise gateway
I use basic authorization mode.
Appreciate any suggestions

Hi,
I am also facing the same issue while trying Impala as Get Data, som certificate issue coming.
Power BI Desktop - Version: 2.67.5404.981 64-bit (March 2019)
Impala - CHD' Impala Kerberos authentication
As per my understanding, Microsoft built in ODBC driver not able to handshake properly with Impala.
What I mean here Microsoft built in ODBC driver' have their own *.pem file however Impala have their own *.pem file.
To understand in more detailed I also enable trace for Power BI Desktop
If you read below log out it is very clearly mentioned that
"ERROR [HY000] [Microsoft][DriverSupport] (1100) SSL certificate verification failed because the certificate is missing or incorrect"
So please advise how we can specify Impala' PEM file to Microsoft ODBC built-in driver to use for authenticating to the client.
Please also note that I have a local certificate which available to my desktop.
Just for courtesy, I installed the latest version on Power BI Desktop to fresh Virtual Machine, but same error also there.
It's highly appreciated for helping here.
Thanks.

Based on my last experience Power BI build in drivers for Impala doesn't work. Alternatively, you download Cloudera ODBC drivers from their site and use ODBC connection in get data in Power BI, then you will be able to use these drivers.
Disadvantage of this is you cannot use direct query. ODBC doesn’t allow for this. So, if I have terabytes of data I am not able to use Impala with PBI. At this moment I do not have solution for this.
