CDP and Polybase - is it possible?

Explorer

Hi,

 

I would like to read data from our Cloudera CDP Cluster. I see, only old Hortonworks, and earlier versions of Cloudera is officially supported. But some tried this? Our Cluster is kerberized. What to write in jaas.conf on Windows? 

I'm geeting this error when executing a CRETE EXTERNAL TABLE:

Msg 105036, Level 16, State 1, Line 21
External Data Source information could not be retrieved due to an internal error Error occurred while accessing HDFS: Exception of type 'JNI.JavaExceptionCheckException' was thrown. Java exception message:
Kerberos login failed (LoginContext.login) with provided principal/password..

Should I have the same user in jaas.conf?

 

T-SQLs executed:

CREATE DATABASE SCOPED CREDENTIAL x with IDENTITY ...

CREATE EXTERNAL DATA SOURCE [Cloudera_Cluster] WITH ...,CREDENTIAL =x

CREATE EXTERNAL TABLE hadoop.employees (....

 

BR,

Gabor
