[ANNOUNCE] New Impala ODBC Driver Released


[ANNOUNCE] New Impala ODBC Driver Released

Cloudera Employee

Hello CDH Users,


We are pleased to announce the release of Impala ODBC v2.5.39. The release has the following fixes and enhancements:


Enhancements & New Features:

  • Restrict catalog functions to current schema. If a schema is not specified for a catalog function, or a schema is specified with the wildcard character %, you can choose to restrict the catalog function to the current schema. This may improve performance. To do this, select the Restrict Metadata with Current Schema GUI option, or set the Current Schema Restricted Metadata connection setting to 1.


Resolved Issues

  • The driver incorrectly adds a length to all the type name in CAST statements during query translation.

  • In the driver log, the driver is reported as read-only, despite being read/write enabled.

  • The driver does not correctly retrieve infinity value for FLOAT columns.

  • The driver does not correctly retrieve NaN (Not a Number) value for FLOAT columns.
