[ANNOUNCE] New Impala ODBC and JDBC Drivers Released


[ANNOUNCE] New Impala ODBC and JDBC Drivers Released

Cloudera Employee

We are pleased to announce the release of Impala ODBC v2.5.40 and Impala JDBC v2.5.41.  The release has the following fixes and enhancements:


Impala ODBC 2.5.40

Enhancements and New Features in Impala ODBC 2.5.40

  • The drivers now supports Impala versions 1.0.1 through 2.9.
  • You can now set configurations options so that they apply to every connection that uses the driver. Before, most configuration options had to be set individually for each connection.
  • The DelegationUIDCase property has been renamed. It is now called DelegationUserIDCase.
  • The driver now automatically canonicalizes the server SPN when using Active Directory Kerberos.


Resolved Issues in Impala ODBC 2.5.40

  • On macOS, the driver sometimes terminates unexpectedly when authenticating the connection through Kerberos.
  • Driver installation failing on Linux has been resolved. The issue occurred because the RPM file used an incorrect path for the installation directory.
  • If a query contains a scalar subquery, the driver returns an error and fails to execute the query.

Impala JDBC 2.5.41

Resolved Issues in Impala JDBC 2.5.41

  • In some cases, the driver throws a “Metadata Result Set Error” when executing COMPUTE INCREMENTAL STATS statement consecutively.
