How does the Impala Driver handle Arrays, Maps, and Structs
The driver only supports retrieval of Arrays, Maps, and Structs in Native Impala SQL.
Which version of SSL does the driver use
The SSL version that the driver supports depends on the JVM version that you are
using. For information about the SSL versions that are supported by each version of
Java, see “Diagnosing TLS, SSL, and HTTPS” on the Java Platform Group ProductManagement Blog.
The SSL version used for the connection is the highest version that is supported
by both the driver and the server, which is determined at connection time.
