Hi Sebastian, thank you for your answer.

You are right, SQL endpoint uses the same metastore as the other clusters. Therefore, after creating a JDBC table in a high currency cluster, I do see the table in the sql analytics workspace. The table is recognized and the schema is even visible. However, when querying the table , an error occurs explaining than JDBC is not supported, only text based file are. The same query works correctly when using the high currency cluster.
