We are pleased to announce the release of Impala JDBC v2.5.37 and Impala ODBC v2.5.37 drivers. This release has the following fixes and enhancements:
Cloudera JDBC Driver for Impala 2.5.37
Enhancements & New Features
- Specify asynchronous exec poll interval. You can now specify the time in milliseconds between each poll that the driver makes for the query execution status. Specify the number of milliseconds in the Advanced Options dialog box in the Async Exec Poll Interval field, or in the AsyncExecPollInterval configuration option.
- Support for Impala 2.8. The driver now supports Impala versions 1.0.1 through 2.8.
Resolved Issues
- Update/Delete statements require a semicolon at the end.
- Conflicting information in documentation regarding CDH.
Cloudera ODBC Driver for Impala 2.5.37
Enhancements & New Features
- Specify asynchronous exec poll interval. You can now specify the time in milliseconds between each poll that the driver makes for the query execution status. Specify the number of milliseconds in the Advanced Options dialog box in the Async Exec Poll Interval field, or in the AsyncExecPollInterval configuration option.
- Support for Impala 2.8. The driver now supports Impala versions 1.0.1 through 2.8.
- Specify Kerberos hostname canonicalization. By default, if you specify a Kerberos realm, the Kerberos layer canonicalizes the host FQDN in the server’s service principal name. You can disable this behavior by disabling the Canonicalize Principal FQDN option, or by setting the ServicePrincipalCanonicalization connection property to 0.
- Configure SSL certificate revocation check. You can now configure the driver to check whether a TLS/SSL certificate stored in the Windows Trust Store has been revoked. By default, the driver checks for revocation. To disable the revocation check, clear the Check Certificate Revocation check box, or set the CheckCertRevocation key to 0.
- Simplified MIT Kerberos configuration. When using MIT Kerberos to access the Impala service from a Kerberos realm that is different than the Kerberos realm that the user belongs to, the user is no longer required to add the Impala service's network domain to the Kerberos realm mapping in the Kerberos configuration file on the client machine.
- Upgraded OpenSSL library. The driver now uses OpenSSL 1.0.2. Previously, the driver used OpenSSL 1.0.1l.
Resolved Issues
- Conflicting information in documentation regarding CDH.
- Incorrect driver version verification instructions for macOS in documentation.
- Segmentation fault in Driver Manager detection on Linux and Solaris Sparc platforms.
- Queries using DISTINCT run correct in HUE but not via ODBC.
- Driver converts COALESCE function to less efficient Impala CASE statement.
- When attempting to use the Windows trust store on Windows Server 2016, an access violation exception occurs.
