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 CDH4.

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.

    That's great news. I am expecting better performance than Shark even for
    the first-time query.

    Thanks,
