Dear CDH, Cloudera Manager, and Cloudera Impala users,
We are pleased to announce the general availability of Cloudera Impala 1.2.2 and version 2.5.13 of the Cloudera ODBC Driver for Cloudera Impala.
Impala 1.2.2 provides key enhancements including a number of the most requested features:
Cost-based join order optimizations
Compute statistics for tables and columns directly from Impala
Preliminary support for clients to securely and more easily authenticate with their username and password via LDAP or Active Directory
Cloudera ODBC Driver for Impala version 2.5.13 includes:
Ability to authenticate with a username and password
Ability to secure client traffic via encrypted SSL
Ability for multi-tiered applications to proxy via delegation IDs
Note that Impala 1.2.2 does not work with Cloudera Manager 4.7 or earlier. If your environment is managed by Cloudera Manager, you should upgrade to Impala 1.2.2 and Cloudera Manager 4.8 together.
