Resolved Issues
The following issues were resolved in Cloudera JDBC Driver for Apache Hive 
2.6.1.

 * [00115543] [IMPJ-354] A string literal after a back-tick ( ` ) is treated 
   as a comment.

 * [00115424] [IMPJ-355] When the driver attempts to connect to the server 
   using Beeline, an error occurs on the server and an exception is logged 
   by the driver. 

   This issue has been resolved. Now, when connecting to the server using 
   Beeline, connection properties such as "driver" and "url" are no longer 
   treated as configuration properties for the server, and the driver does 
   not send SET queries to the server with these properties.
