3164235 - Does Smart Data Integration (SDI) Impala Adapters support security property UseSasl?

• Installed the ImpalaAdapter and try to establish the connection using Kerberos.
• The connection is required to use SASL. There does not seem to be a parameter in the graphical remote source configuration.
• Tried to create the remote source using SQL (and guessing SASL parameters).
