Dear CDH, Cloudera Manager, and Cloudera Impala users,
We are pleased to announce the general availability of Cloudera Impala 1.3.1 for use with CDH 4.
Impala 1.3.1 contains stability enhancements and the following new features:
Improved memory usage under contention including higher concurrency, high numbers of Parquet columns, or low memory limits
Additional SQL built-in functions
Note that Impala 1.3.1 does not work with Cloudera Manager 4.7 or earlier. If your environment is managed by Cloudera Manager 4.7 or before, you should upgrade to Impala 1.3.1 and Cloudera Manager 4.8 together.
