Announcing: Cloudera Impala 1.2.3

Master Collaborator

Dear Cloudera Impala users,


We would like to announce the general availability of Cloudera Impala 1.2.3. This release fixes a bug where Impala couldn’t read Parquet files written by MapReduce.


Note that Impala 1.2.3 does not work with Cloudera Manager 4.7 or earlier. If your environment is managed by Cloudera Manager, you should upgrade to Impala 1.2.3 and Cloudera Manager 4.8 together.
